The differentia l pressure before and after the valve shall be higher than that of the throttle. Working principle After the controlled medium enters the valve, the before-valve pressure P1 is input into the lower diaphragm chamber through the control pipeline, and the pressure Ps after throttling by the throttle valve is input into the upper diaphragm mchamber. The difference between P1 and Ps △Ps=P1-Ps is called effective pressure. The difference between the thrust producedon the diaphragm by P1 and the thrust produced on the diaphragm by Ps determines relative positions of the plug and seat and determines the flow that passes through the valve. When the flow that passes through the valve increases, i.e. △Ps increases, P1 and Ps respectively acts on the lower diaphragm chamber and upper diaphragm chamber to make the plug move towards the seat, so that the flow area between the plug and seat is changed and Ps is increased . The thrustacted on the diaphragm by the increased Ps, the reacting force of the spring and the thrust acted on the diaphragm by P1reaches balance at the new position to realize the purpose of controlling f low, and vice versa. The flow of the controlled medium is determined through adjusting relative positions of the throttle valve and seat. Calibration chart: To set the flow more accurately and quickly, the following calibration charts are offered for you reference (please measure the flow with a flow meter if you need to set the flow more precisely or set the flow for valves with DN150-250). The calibration chart is only applicable to water, and serves as a reference for other media, whose flow shall be properly adjusted in the actual process.. I.

10D Series control valve

The 100 series control valve design features Innovative packing structure design The top guided structure design Detachable structure design Standard modular design Reading tips For detailed product information, product animation, please click "contact us", then visit the company's website, Download and reading Or contact us directly Outline The 10D Series multi-hole low noise control valve adopts the sleeve guided structure and pressure balanced plug. It is a high performance control valve with good dynamic stability that is suitable for severe service conditions. As the differentia l pressure in the service conditions is relatively high and the flow velocity of media is high, the trims will be severely eroded and damaged and high noise will be produced. Therefore, we change the standard window-type sleeve into the multi-hole sleeve. For liquids, the flow direction is generally high-in and low-out, and multi-hole throttling makes the media carry out collision inside the sleeve, so as to consume internal energy and reduce flow velocity . For gas media, the flow direction is generally low-in and high-out, so that the gas media achieve volume expansion at the back of the seat after throttling by the multi-hole sleeve and the pressure of media is reduced to lower the flow velocity. The parts of the101D Series are interchangeable with those of the 101T Series control valve except that the sleeve is changed into the multi-hole type. Parameters of control valves: DN 15~450mm PN Class150~2500 Applicable temperature range -30℃- 260℃(single-seat structure) -196℃- 570℃(double-seat structure) Trim features sleeve guided type, balanced trim structure, with balanced seal ring structure Body type straight-through type, angle type.

10G Series control valve

Outline The 10G Series cage double-seat control valve adopts theageuided structure and pressure balanced plug. Different from the 10T Series, this kind of control valve adopts the cagedouble-seat structure and is mainly used in applications that do not have high requirements for shut-off class. As it adopts the double-seat structure, and the two sealing faces are metal seals, the temperature range is wider. The plug makes use of the pressure balanced structure, the opening and closing force is low and the media under service conditions with high differential pressure can be controlled through relatively low actuator thrust. It is widely used for fluid control on pipelines of middle and low temperature and middle and low pressure that require good dynamic stability. With such features as good sealing performance, high allowable differential pressure, cage guiding, large guiding area, good stability and compact structure, it can realize fast replacement of trims on the line with high maintenance efficiency, saving manpower and time. The balanced plug structure makes sure that the actuator thrust required is the lowest.

10M Series control valve

Outline The 10M Series balanced labyrinth control valve adopts the labyrinth cage and balanced plug design. The labyrinth sleeve is composed of cylindrical discs with many coaxially distributed labyrinths. According to different technological parameters of the media, different labyrinth specifications and piling layers are designed to form the cage and the cage designed to form the cage and the cage divides the whole flow channel into several tiny circuitous or step flow channels, forcing the fluids to continuously change the flow direction and flowing area and gradually reducing the pressure of fluids, so as to prevent the occurrence of flash evaporation and cavitation and prolong the service life of the trim. The balanced sleeve plug is adopted. The closely fit plug and seat ensure very low leakage. The trim is suitable for service conditions under which blocked flow will easily be produced and cavitation will be caused. Parameters of control valves DN 20~450mm PN Class150~2500 Applicable temperature range -30℃～260℃ (single-seat structure) -196℃～570℃(double-seat structure) Trim features sleeve guided type, balanced trim structure Body type straight-through type, angle type Bonnet type standard type, heat dissipation type, cryogenic type Flow characteristic equal percentage, Linear, quick open Shut-off class ASME B16.104 V (standard metal seat) AS ME B16.104 V I (shut-off soft seat) Pipe connection type flange type, Butt welding type Actuator type pneumatic diaphragm actuator pneumatic piston actuator Electric actuator Exploded view of 10M Series Speed control principle of labyrinth control valve The valve that is damaged by cavitation, flash evaporation, vibration and noise produced by the media that passes through the valve at a high flow velocity is the main cause that leads to failure of control in the system. Even if the valve is not damaged, bad process control caused by too high noise and severe vibration will lower product performance and influence the running capacity of the equipment. Based on the principle of fluid mechanics,the labyrinth control valve adopts speed control principle and technology and makes use of multi-stage pressure drop to eliminate cavitation, flash evaporation, vibration, noise, etc .,providing overall system control solutions form any different application fields.Under severe service conditions, bad performance of valves is caused by too high flow velocity. The maximum flow velocity of the fluids in the valve always occurs at the throttling face(figure1) which is at the downstream side of the restriction orifice of the plug .Even if materials of relatively high hardness are used in the valve to control the damage caused by cavitation ,only a small amount of faults in the valve caused by too high flow velocity of the media can be eliminated. The flow velocity of media in all valves must be controlled so as to maintain the performance and reliability of the valves. The labyrinth flow channel can realize control of flow velocity The labyrinth control valve can prevent the plug from producing high flow velocity and ensure the final control effect: The medium pressure and flow velocity can be effectively controlled during the whole travel of the valve .The labyrinth cage scatters the fluids into several split flow to reduce the flow velocity as much as possible (figure2). Each fluid channel is composed of specific quantities of right-angled bends that form the labyrinth flow channels(figure3). During the process, each bend will reduce the flow velocity of the flowing media to a certain extent .The bend number N is the number that is required for scattering the maximum differential pressure in the plug (figure4). See the following formulas: Cause of cavitation When the fluid pressure is reduced to The saturated vapor pressure or lower, flash evaporation or bubbles will occur. In most control valves(figure5), the inlet pressure is P1, velocityisV1. When the fluid passes through the plug necking area, the velocity is increased to Vvc . According to the principle of conservation of energy, the fluid pressure suddenly drops to Pvc .When Pvc is equal to or less than the liquid saturated vapor pressure Pv, the liquid will be gasified and bubbles will be produced, so that flash evaporation occurs. After the fluid passes through the plug, the pressure starts to be restored and the kinetic energy is transferred into potential energy again. When the pressure is restored to the downstream pressure, which is expressed as P2 and the velocity is V2. When the restored pressure exceeds the saturated vapor pressure Pv, the bubbles formed will be broken and cavitation will occur. This kind of energy release will increase the partial stress to be above 200000PSI (1400MPa) and the stress will rapidly destroy the solid plug. Solution to cavitation The labyrinth control valve can effectively eliminate the damage caused by failure of control of fluid velocity. First, the fluids are scattered into many small flow channels. Thus, even the bubbles are formed ,their volume is very small and the energy is not sufficient to produce stress that can damage materials. Secondly, the flow velocity is maintained at the lowest level .Thus ,the partial pressure will not be reduced to be lower than the fluid vaporizing pressure. Therefore, cavitation will not occur. The damage caused by cavitation is a typical signal that indicates failure of control of flow velocity .As is mentioned above, the adoption of materials of high hardness, insulating sleeve or downward orifice will only eliminate as mall amount of faults in the valve caused by cavitation. The high flow velocity will cause cavitation and damage the plug ,and the solution to cavitation is to adopt the labyrinth cage as shown in figure 6. According to the fluid evaporation pressure ,the flow velocity can be achieved through the following formulas: Design of labyrinth disc of labyrinth control valve Determine the bend number N and select the number to ensure the flow velocity when the fluid flows out of the flow passage. Each cage forms multi-layer labyrinth groups (figure7) by adopting special technology .The labyrinth discs are processed into several flow channels similar to the labyrinth through special forming technology (figure8). According to different service conditions, after precise calculationand in combination with CFD flow filedanalysis (figure9), each flow channel is designed with a series of right-angled bends of specific quantity to provide resistance for media and reduce the velocity stably. The technology can fully control the velocity of media in all channels of labyrinth discs, so that the media can flow at the controllable velocity within the whole range. To achieve the flow characteristic required by the system, a labyrinth group shall be composed of 3kindsof labyrinth discs .To meet the requirements of high differential pressure and small flow, the discs at the bottom shall have few flow channels and many bends. The middle labyrinth discs shall have medium flow channels .To meet the requirements of low differential pressure and large flow, the discs at the top shall have many flow channels and few bends. The resistance, quantity and area of all flow channels in the labyrinth control valve can be customized according to the specific applications so as to control flow velocity, eliminate cavitation ,flash evaporation, vibration, noise and etc. that occur during the use of fluids. Selection of flow direction of labyrinth control valve For liquid media, the flow direction is side-in and bottom-out. For gas and steam media, the flow direction is bottom-in and side-out. This is because that the liquid is an incompressible fluid. By adopting side-in and bottom-out, the high speed liquids at the exits of all flow channels of labyrinth discs will carryout mutual collision on the central axis of the labyrinth sleeve, counteract their energy and form buffer cushion, so as to further lower flow velocity and reduce the erosion of the valve and trim by high speed liquids. The high differential pressure gas and steam are compressible fluids .After pressure drop by the labyrinth discs, the volume expands sharply. This requires that the flow cross-sectional area at the exit should be higher than that at the inlet. Therefore, the flow direction shall be bottom-in and side-out .Otherwise, the pressure drop effect will be influenced.

Selection of flow direction of labyrinth control valve For liquid media, the flow direction is side-in and bottom-out. For gas and steam media, the flow direction is bottom-in and side-out. This is because that the liquid is an incompressible fluid. By adopting side-in and bottom-out, the high speed liquids at the exits of all flow channels of labyrinth discs will carryout mutual collision on the central axis of the labyrinth sleeve, counteract their energy and form buffer cushion, so as to further lower flow velocity and reduce the erosion of the valve and trim by high speed liquids. The high differential pressure gas and steam are compressible fluids .After pressure drop by the labyrinth discs, the volume expands sharply. This requires that the flow cross-sectional area at the exit should be higher than that at the inlet. Therefore, the flow direction shall be bottom-in and side-out .Otherwise, the pressure drop effect will be influenced.

The cage adopts the press-in type seat design, which solves the problems of difficult disassembly and high leakage of the traditiona l thread screw-in type seat and prolongs the service life. The flow to open design is adopted, and the medium flow direction tends to the opening direction of the valve with good controllability of small opening and low flow characteristic distortion. Special cages with noise reduction and anti- cavitation functions can be offered according to the requirements in different service conditions. Parameters of control valves DN 15~450mm PN Class150~2500 Applicable temperature range -196℃- 570℃ Trim features Top guided, unbalanced trim, quick disassembly cage structure Body type straight-through type, angle type. Bonnet type standard type, heat dissipation type, cryogenic type, bellows Flow characteristic equal percentage, linear, quick open Shut-off class ASME B16.104 V (standard metal seat) ASME B16.104 V I (shut-off soft seat) Pipe connection type flange type, butt welding type Actuator type pneumatic diaphragm actuator pneumatic piston actuator Electric actuator Exploded view of 10P Series Bonnet type 1 Standard bonnet The standard bonnet is normal temperature upper bonnet. The bonnet material is the same as that of the body, playing the function of sealing the body and linking the actuator. Working temperature: -30℃- 230℃ 2 High temperature bonnet The high temperature bonnet is specially designed for high temperature service conditions. The heat sink enhances the contact area between the bonnet and the surrounding air so as to play the function of heat dissipation. It can effectively protect the packing and actuator. Working temperature: +230℃~ 530℃ or -45℃~ -5℃ 3 Cryogenic extended bonnet The cryogenic extended bonnet is suitable for media under low temperature status (such as liquid oxygen, liquid nitrogen). This kind of upper bonnet can effectively protect the packing and actuator. The standard material adopted is 304 or 316. Materials of different expansion coefficients can also be adopted according to different service conditions Working temperature: -196℃- 45℃ 4 Metal bellows seal bonnet The metal bellows seal bonnet is installed with the stainless steel bellows assembly to isolate the media from the outside and ensure the stem will make upward and downward movement. In addition, the upper bonnet is also provided with the standard packing box to ensure the media will not leak and cause waste or produce pollution to the environment. Working temperature: -60℃- 530℃ Materials for main parts Part name Material Body 、bonnet WCB、WC6、WC9、CF8、CF8M 、CF3、CF3M Plug, seat 304、316、316L、410、420、17-4PH、Monel, Hastelloy Cage CF8、CF8M Stem 304、316、316L、420、17-4PH Note: Special materials can be offered according to customer requirements. Packing structure As a seal at the stem, the packing plays the sealing function for the upward and downward movement at the stem. The traditional solution is the pressing board type packing box structure. Although this structure can play the sealing function, the problem that high friction at the stem will cause big dead band, no response and small signal still exists. To solve the above problem, the 100 Series control valve is designed with the new type packing box structure based on the principle of ensuring effective sealing at the stem, improving the structure and reducing stem friction. The structure has such features as: The integral packing box is easy to replace and repair. Many U type seal rings with sealing compensation function replace the traditional PTFE V type packing. Standard packing box structure The integral packing box is the standard packing structure. It is easy to replace and repair with the modular design. Working temperature: -30℃ - 260℃ The packing is composed of many U type seal rings with sealing compensation unction. High temperature packing box structure The V type flexible graphite serves as the high temperature packing. Working temperature: -45℃ - 530℃ The high temperature packing is composed of three V type graphites of different tapers. Bellows packing box structure The bellows stem sealing structure often adopts the bellows. The standard packing box with dual sealing will absolutely seal toxic and cryogenic media. Working temperature: -60℃ - 530℃ The metal bellows isolates the media fromthe outside, and ensures the stem makes upward and downward movement. Working pressure and temperature range of sealing materials Type Material temperature range standard PPL -30℃- 260℃ PTFE -30℃- 230℃ high temperature V type flexible graphite -30℃- 540℃ PTFE -50℃- 250℃ bellows seal 304/316 -196℃- 400℃ Hastelloy C/ MO ENEL -250℃- 530℃ Gasket The 100 Series is a new generation high performance control valve. It adopts self aligning insertion type thread less seat, which is fixed axially by the bonnet and cage. Metal-to-metal contact between the bonnet and body and between the seat and body is realized. The gap between them is filled by the packing gasket and sealing is realized. The compression degree of the bonnet sealing gasket is determined by the bolt pre-tightening force on the bonnet. Only after the concentricity between the bonnet and body is ensured, will it be ensured that the plug and seat are vertically aligned so as to meet the strict sealing requirement. When the bonnet is completely installed, its force is transferred to the seat through the cage or sleeve. Only when the height tolerance of seat, cage or sleeve is very close, will the sealing gasket of the seat achieve proper compression, so that sealing is ensured and no leakage is caused due to over pressure on the sealing gasket of the seat . If the valve is correctly assembled, the self aligning seat with the top guided structure will fit well with the plug without the need of grinding. Various gasket materials and working temperature range Type Material Temperature range Flat gasket(for general purpose) PTFE -130℃～150℃ Serrated gasket (for high temperature and high pressure) 304/316 -196℃～500℃ Spiral wound gasket (for high temperature and corrosion) 304/316+flexible graphite -196℃～500℃ The sealing gaskets made of special materials can be used under higher temperature. Seal ring solutions in the balanced trim The balanced seal ring is mainly used in the balanced trim to play the sealing function. It is a core technological part in the sleeve type control valve. T he balanced trim type control valve produced by our company provides three kinds of seal rings for users. Introduction to the balanced seal ring •The spring actuated PTFE seal is a high performance seal that is assembled w ith special spring in the U PTFE. •The proper spring force and the fluid pressure in the system will eject the seal lip and slightly press the sealed face so as to achieve excellent sealing effect. •The seal lip is short and thick, which is the best feature, so as to reduce friction and prolong the service life. Features of the balanced seal ring •Used for reciprocating and rotating movements. •Suitable for most fluids and chemical products •Low friction coefficient •Without the occurrence of crawling during precision control, the dead band of the valve is reduced. •Good anti-wear performance and size stability •Adapting to sharp temperature change •No pollution Selection of sealing materials Seal ring type Material Working temperature Balanced seal ring PPL -30～260℃ Graphite seal ring Flexible graphite -196～500℃ Metal seal ring INCONEL 718 -196～560℃ Flow characteristic The flow characteristic of the control valve is the relationship between the flow of the incompressible fluid that passes through the control valve and the opening of the control valve when the differential pressure at the two ends of the valve is invariable. This flow characteristic is called inherent flow characteristic. Linear flow characteristic It indicates that the flow and opening of the control valve are in t he linear relationship. It is usually used for applications w ith small change of differential pressure, which is almost invariable. When the pressure drop on the valve becomes the main pressure drop in the system, the linear flow characteristic is often used。 Equal percentage flow characteristic: It indicates the flow change rate caused due to the change of travel is in direct proportion to the original flow at the point. It is usually used in applications that require relatively wide adjusting range, or w hen the system pressure loss is much higher than that of the valve, or when the opening change and differential pressure change on the valve is relatively high. Quick open It is mainly used for on-off control system. It is required that the flow should be high when the opening is small, and with the increase of the opening, the flow w ill reach the highest value very soon. After that, if the opening increases again, the change of flow is very title.

Through the control pipeline, P1 is input to the upper diaphragm chamber of the actuator and acts on the top disc. The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly. At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure. When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut. I.

The medium produces an acting force on the detection element, which balances the pre-tightening force of the preset spring (8). When the pressure in the tank drops to be lower than the pressure set point of the nitrogen supply device, the balance is destroyed, so that the pilot plug (6) is opened, and the before-valve gas enters the upper and lower diaphragm chambers of the main valve actuator (3) after passing through the pressure reducing valve (4) and throttle valve (5). The main valve plug (2) is opened and nitrogen is filled into the tank. When the pressure in the tank rises to the pressure set point of the nitrogen supply device, the pilot plug (6) is closed by the preset spring force. Due to the spring action in the main valve actuator the main valve is closed and nitrogen supply is stopped. The nitrogen discharge device (see figure 2) is an internal feedback mechanism. The medium enters the detection mechanism (2) after passing through the bonnet. The medium produces an acting force on the detection element, which balances the pre-tightening force of the spring (3). When the pressure in the tank rises to be higher than the pressure set point of the nitrogen discharge device, the balance is destroyed, so that the plug (1) moves upward to open the valve and discharge nitrogen to the outside. When the pressure in the tank falls to the pressure set point of the nitrogen discharge device, the valve is closed by the preset spring force. 1.

Taking the seat as the starting point, the eccentric disc produces a function similar to that of the cam and the disc can be pulled to leave the seat without the need of using too high operating force. The function of the disc similar to that of the cam at the starting position reduces the abrasion of the seat and reduces the deformation of the seat. When the valve is opened , the disc will instantly leave the seat, and when the valve is closed, the function similar to that of the cam turns the rotary movement of the valve into linear motion, so as to effectively push the disc to contact the seat. The built-in compensation spring can effectively compensate for the abrasion of the sealing seat and enable the sealing seat to be elastic during the opening and closing process, greatly reduce friction ,enhance sensitivity and make the whole valve have excellent shut-off and control functions. Seat design The 70E Series provides various types of seat structures: 1. The seat adopts the internally opened U groove structure .Self sealing is realized through medium pressure . The built-in compensation spring makes the sealing structure realize real dynamic sealing through the medium pressure in the system .Seat leakage: under CV*10%. 2. These at adopts externally opened O ring groove structure . When the disc is not completely closed, the seat has certain radial flexibility so that the seat abrasion is reduced and the torque is lowered. When the disc is closed, the pre-tightening force of the sealing face of the disc is offered to ensure sealing. Seat leakage: under CV*10-6%.
