Pneumatic cut-off valve industry characteristics of pneumatic valve _ pneumatic components factory

Pneumatic valve pneumatic components factory production of pneumatic valve industry to cut off the pneumatic valve is a second chip structure of pneumatic valve, the valve is the main and deputy of two parts, pneumatic core adopts full size, large rated flow coefficient, small flow resistance, pneumatic core surface hardening treatment with a special process, and make its smooth surface wear resistance; Increase type ptfe sealing materials for carbon fiber, has good cutting performance, good seal, long life and other characteristics; Selects the high performance double piston actuator gear rack mechanism, high transmission efficiency, compact structure. Pneumatic cut pneumatic valve technical parameters: nominal pressure: PN1. 6 ~. 4 mpa range: DN15 ~ 300 mm medium temperature: - 60 ℃ ~ + 250 ℃ pneumatic cut pneumatic valve is widely used in petroleum, chemical, pharmaceutical, metallurgical, textile, paper and other production departments of the medium inside the gas, liquid pipeline cut off or open, meet the technological requirements. Pneumatic cut pneumatic valve features: (1) seat limit structure ( Torque stable) And limit: seat sealing reasonable preload, greatly reduces the operating torque. (2) stem blow-out proof design ( Safe and reliable) : bottoms type valve stem, prevent stem fly out by medium pressure is too high, eliminate the safety hidden trouble. (3) the unique fire prevention design ( After the fire to keep seal) : seat is a modular seat sealing surface of stainless steel package ptfe sealing ring, stainless steel seat sealing surface and a small gap between the aerodynamic body. When ptfe sealing ring in the fire burned, the role of stainless steel in spring to pneumatic, pneumatic and sealing is formed between the stainless steel seat sealing surface. (4) antistatic device ( Electrostatic raises) can be Simple: drag the anti-static device, pneumatic body, valve stem and valve body is an organic whole repeatedly, sealing surface friction caused by static electricity is caused by the switch leads. (5) standard actuators ( Pneumatic piston, electric) Interchangeable. : Q641F/H pneumatic cant cut pneumatic valve working principle of the pneumatic valve working principle of chlorine gas emergency shut-off valve, Dynamic figure)
