Performance:

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 the opening action. It is mainly used as a shut-off valve. It can also be designed to have the function of regulating or segment valve and regulating. More and more are used on medium caliber pipes. 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 the pneumatic butterfly valve are simple structure, small size, light weight and low cost. This feature of the pneumatic butterfly valve is particularly remarkable. It is installed in a high-altitude dark passage and is easily controlled by a two-position five-way solenoid valve. It can also adjust the flow medium.
