Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! A pneumatic valve Wafer Product Overview Q671F / PPL Wafer ball valve pneumatic pneumatic valve series is a product, also known as slim pneumatic valve. Italy is the introduction of technology and the development of domestic design a new generation of ultra-short flange distance ball, ball core channel has a rectangular shape, V-shaped and O-shaped. Q671F / PPL pneumatic valve on the folder with a compact, small size, light weight, easy installation features. Pneumatic Wafer ball is absorbed by the domestic Italian technology and design and development of a new type of ultra-short flange distance ball. It uses a thin pneumatic valve actuators connected direct connection, with a compact, small size, light weight, small friction, hysteresis is small, stable and reliable operation, Q671F / PPL pneumatic valve on the folder can be widely used in petroleum, chemical, metallurgical, power, light industry and other fields, oil, water, gas and pulp or fibrous fluid controls automatically adjust or cut. Second, the pneumatic valve on the main technical parameters of the folder nominal diameter DN10 ~ 150mm Nominal PN1.6 2.5 4.0 MPa (high pressure can be customized) leakage soft sealing: zero leakage hard seal: ≤ nominal flow rate of 10-5 actuators GT, SR , ST, AT, AW series of single and double acting pneumatic actuators fast opening flow characteristic feature adjustable range DN10-80 DN100-150 250: 1 350: 1 body in the form of a monolithic forging, casting monolithic thin flange connection form of Clip-on spool form 'O' type poppet packing V type PTFE packing, flexible graphite packing, etc. Suitable temperature sealing surface PTFE≤180 ℃, PPL≤300 ℃, hard seal ≤450 ℃ configuration actuator models GT , SR, ST, AT, AW series of single and double acting pneumatic actuator control mode switch two controls, 4-20mA analog control three, pneumatic valve actuators on the technical parameters of the folder actuator model GT, SR, ST, AT, AW series of single and double acting pneumatic actuator supply pressure 0.4 ~ 0.7MPa Air Connection G1 / 4 ', G1 / 8', G3 / 8 ', G1 / 2' Ambient temperature -30 ~ + 70 ℃ action in the form of single-acting actuators Agency: Air-to-close (B) - When the loss of gas valve opening (FO); open air (K) - when the loss of gas valve closed (FC) double acting actuators: air-to-close (B) - When the loss of the gas valve to keep (FL); open air (K) - loss of gas when the valve position to maintain (FL) can be equipped with accessories positioners, solenoid valves, air filter pressure reducer, to secure his position valves, limit switch, valve position transmitter, the four hand wheel, pneumatic valve on the main part material sandwiched Part Name Material Body WCB 304 (CF8) 316 (CF8M) 316L (CF3M) sphere 2Cr13 + nitriding 304 316 316L valve stem 2Cr13 304 316 316L Block seals PTFE (polytetrafluoroethylene), PPL (PPL), a metal seal (carbide) V-type PTFE packing PTFE packing, flexible graphite five, pneumatic valve performance specifications for the folder nominal diameter DN (mm ) DN15-150 Nominal pressure PN (MPa) 1.0 1.6 2.5 4.0 1.5 2.4 Test pressure strength test seal test 1.1 3.75 6.0 1.76 2.75 4.4 0.5 0.7 low pressure tightness test applicable to medium water, oil, steam, nitric acid (temperature ≤200 ℃ ), acetic acid class (temperature ≤200 ℃) Haiqiao Yap valve to provide you with a professional [Q671F / PPL pneumatic valve on the folder / pneumatic valve] solutions thin, if you have any questions, we will try our best to answer your questions!
