Pneumatic Butterfly Valve Structural

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a kind of pneumatic valve which can be opened and closed with the round butterfly plate rotating with the valve stem to realize the start-up action. It is mainly used as block valve, and can also be designed to have the function of regulating or section valve and regulating. Butterfly valve is more and more used in low-pressure large and medium diameter pipeline.

Pneumatic Butterfly Valve Characteristic

Pneumatic butterfly valve features: 1, compact and light, easy disassembly and maintenance, and can be installed in any position. 2. Simple and compact structure, low operating torque, 90 ° The swing opens quickly. 3. The flow characteristics tend to be linear and the regulation performance is good. 4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage point. 5. The butterfly plate can be coated according to the user’s requirements, such as nylon or PTFE. 6. The valve can be designed as flange connection and pair clamp connection. 7. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve.

Pneumatic Butterfly Valve Application

Pneumatic butterfly valve classification: 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, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly significant. It is installed in the high altitude underpass and controlled by two position five way solenoid valve. It is easy to operate and can also adjust the flow medium.
