With multi spring actuator, has the advantages of simple structure, light weight, small volume, convenient disassembly and assembly. It is widely used to accurately control the process of gas, liquid and other media, such as pressure, flow rate, temperature, liquid level to keep in the given value. Suitable for a kind of fluid through the three-way valve into two outflow or management of two kinds of fluid through the three-way valve combined into a fluid occasions pneumatic film three-way regulating valve with three-way and three-way shunt two kinds. Nominal pressure PN16, 40, 64; Nominal diameter range DN25 -- 300. Suitable for fluid temperature from -60ºC to +450ºC. The leakage standard is class5 The flow characteristics are linear and parabolic.Pneumatic film three-way regulating valve main parts materialsValve body, valve cover: HT200, ZG230-450, ZG1Cr18Ni9TiSpool, valve seat: 1Cr18Ni9TiCorrugated diaphragm: acrylonitrile rubber clip reinforced polyester fabricPacking: polytetrafluoroethylene, flexible graphiteSpring: 60Si2MnMembrane cover: A3Valve stem and push rod: 2Cr13, 1Cr18Ni9Ti Bushing: 2Cr13Gasket: Rubber asbestos sheet, 1Cr18Ni9Ti, asbestos wound gasketPneumatic film three-way regulating valve main technical parameters  Nominal diameter DN (mm)253240506580100125150200250300Rated flow coefficientKvconfluence8.513213453851352103405358001280Shunt     851352103405358001280Rated stroke L (mm)16254060100Effective diaphragm area Ae (cm2)28040060010001600Nominal pressure PN (MPa)1.6, 4.0, 6.4Inherent flow characteristicsStraight line, parabolaInherently adjustable ratio R30:1Operating temperature t (° C)Common type: cast iron -20 ~ 200, cast steel -40 ~ 250, cast stainless steel -60 ~ 250Heat dissipation type: cast steel -40 ~ 450, cast stainless steel -60 ~ 450Temperature difference of two media t (ºC)Cast iron ≤150, cast steel and cast stainless steel ≤200Signal range Pr (kpa)20 to 100Air source pressure Ps (MPa)0.14 to 0.4Allowable leakage l/h10-4 x valve rated capacityAllowable differential pressure △P (MPa)0.860.750.480.310.270.180.110.120.09   Regulating valve order instructionsUser's order needs to provide regulating valve medium, regulating valve before pressure, valve after setting pressure, maximum flow/hour, pressure difference/flow ratio, determine the valve size/connection mode standard maximum stroke open stroke flow regulation ratio pressure fluctuation (precision) pressure/temperature ratio, maximum temperature resistance, valve body material switch state (on and off), pressure grade, internal leakage rate Valve body structure/regulating valve working principle/regulating valve installation instructions and other related technical data when the occasion is very important or the environment is more complex, please try to provide design drawings and detailed parameters, by our Xuan Cheng valve company experts for you to review and check thank you for visiting our website [Xuan Cheng valve company] if you have any questions.
