Product Name: Pneumatic UPVC Ball Valve
Product introduction:

Pneumatic UPVC ball valve is applicable for cutting off fluid with strong corrosion at room temperature. As light weight, strong corrosion resistanceits,it's widely used in pure water and drinking water pipeline system, drainage and sewage treatment pipeline system, salt and seawater pipeline system, acid, alkali and chemical solution system and other industries.

Pneumatic piston actuator is divided into spring-type and spring-free type. When the valve is required to be fully opened or closed under fault, it is equipped with spring type (by restoring tension of spring). When it is required to maintain position under fault, it is equipped with spring-free type.It is mainly composed of cylinder ,body ,spring, piston, rod, front and rear ,cylinder head ,rack output shaft and other components.
Equipped with limit switch box, solenoid valve, filter regulator and other accessories, the switch operation can be realized.

PRODUCT CHARACTERISTICS
