Pneumatic Butterfly Valve

Pneumatic Butterfly Valve

Introduction:

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a kind of pneumatic valve that uses a round butterfly plate rotating with the valve stem for opening and closing to realize the starting action. It is mainly used as a block valve, and can also be designed to have the function of regulating or breaking the valve as well as regulating. Butterfly valves are increasingly used in low-pressure large and medium caliber pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume and light weight, and low cost. The pneumatic butterfly valve is especially prominent. It is installed in the high altitude tunnel, and can be easily controlled and operated by the two position five way solenoid valve, and can also adjust the flow medium.

Characteristic:

1. Small and light, easy to disassemble and repair, and can be installed at any position.
2. Simple and compact structure, small operating torque, and quick 90 ° rotation opening.
3. The flow characteristics tend to be straight, and the regulation performance is good.
4. The connection between the butterfly plate and the valve rod adopts a pin free structure, which overcomes the possible internal leakage point.
5. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. Zero leakage is still maintained after more than 50000 times of opening and closing under pressure.
