Pneumatic fixed ball valve overview

Pneumatic fixed ball valves, pneumatic ball valves, ball valves are two-way valve, the flow of unlimited. The flange is connected with studs, the upper and lower stems are equipped with sliding bearings to reduce friction, the use of labor-saving, smooth. Under normal conditions: when the pressure is low, the valve seat seal relies on the spring pre-tightening force to make the valve seat close to the ball body to seal. When the pressure is high, a piston effect is formed on the valve seat. Under the action of the upstream medium pressure, To seal, fixed pneumatic valve, pneumatic valve, ball valve is widely used in process control system to achieve on or off.
