Features:
Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the stem to achieve activation. It is mainly used as a cut-off valve. It can also be designed to have the function of adjustment or segment valve. The use of medium-diameter pipes is increasing. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard sealing pneumatic butterfly valve, soft sealing pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small size, light weight and low cost. This feature of pneumatic butterfly valve is especially remarkable. It is easy to operate and can also adjust the flow medium.
