UPVC CPVC PVC Pneumatic Actuated Butterfly Valve DN50 2''
The main advantages of pneumatic actuator butterfly valve, simple structure, small size, light weight, low cost, pneumatic butterfly valve this feature is particularly significant, installed in the high-altiude tunnel, through two-five-way solenoid valve control easy to operate, but also can adjust the flow medium.
Pneumatic Butterfly Valve is divided into Spring Returm(Single Acting) Pneumatic Butterfly Valve and Double Acting Pneumatic Butterfly Valve.
Spring Retum(single acting) pneumatic actuator is the spring-driven Piston structure, there are two principles: nomally open(NO) and normally closed(NC), which means that: when air goes in, the valve closed(NO), when air goes in, the valve opened(NC).
Double Acting pneumatic valves need to be equipped with 5-way 2-position solenoid valve to control the air goes into diferent entrance and then control the valve open and close.
When driving the same valve body, the opening and closing speed of double acting is faster than the single acting.
