What Is Pneumatic Butterfly Valve?
Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic actuator 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 and adjustment.
According to the type of actuator, it can be divided into: Single-acting pneumatic butterfly valve and Double-acting pneumatic butterfly valve
According to the material of the butterfly valve, it can be divided into: Stainless steel pneumatic butterfly valve, Plastic pneumatic butterfly valve and Cast iron pneumatic butterfly valve。
According to the connection mode of the butterfly valve, it can be divided into: Wafer pneumatic butterfly valve, Flange pneumatic butterfly valve, Tri-clamp pneumatic butterfly valve and Lug pneumatic butterfly valve
According to the seals of the butterfly valve, it can be divided into: Soft sealing pneumatic butterfly valve and Hard sealing pneumatic butterfly valve
According to the structure of the butterfly valve, it can be divided into: Single eccentric pneumatic butterfly valve, Double eccentric pneumatic butterfly valve and Triple eccentric pneumatic butterfly valve
According to the function of the butterfly valve, it can be divided into: Normal temperature and pressure pneumatic butterfly valve, High temperature pneumatic butterfly valve and Sanitary pneumatic butterfly valve
