Q647F pneumatic valve,

Shanghai crown ring Valve Manufacturing Co., pneumatic valve, Q647F pneumatic valve, ball valve is a two-way valve, the flow unrestricted. Flange connection with studs, upper and lower stems are equipped with sliding bearings, reducing friction, use and effortless operation and smooth. I. Product Overview: fixed pneumatic valve, pneumatic valve, ball valve is a two-way valve, the flow unrestricted. Flange connection with studs, upper and lower stems are equipped with sliding bearings, reducing friction, use and effortless operation and smooth. Under normal conditions: pressure is low seat sealing rely on spring preload ball to seal against the valve seat, the pressure is high, the piston effect on the valve seat is formed at the upper reaches of the media pressure, the seat pressed the ball to seal, fixed pneumatic valve, pneumatic valve, ball valve is widely used in process control system implementation on or off.
