Fire prevention and anti-static design
Valve stem explosion-proof outlet device
The valve ball is designed with a pressure balance hole.
Double-layer valve stem packing and counter-pressure disc type shrapnel device
Product Description:
pneumatic thin ball valve is shorter than that of common flange ball valve, which is suitable for occasions with a large number of valves in the same pipeline as the factory. The sphere has a 90-degree rotation action, and the ball has a circular through hole through the axis. When the ball rotates 90 degrees, it should all appear spherical surfaces at the entrance and exit, thereby cutting off the flow. On the contrary, it also presents a through hole to allow the medium to pass. The full diameter sphere cavity provides a direct flow channel with little resistance for the medium. The rapid rotation of the pneumatic actuator 90 degrees can make the ball valve closed tightly in an instant, and the direct connection between the actuator and the valve body reduces the probability of failure. Flanged pipes can maintain good sealing performance, facilitate maintenance and replacement, and facilitate sealing of pipes.
