Introduction
Pneumatic butterfly valve is one type of butterfly valve assembly which is mounted with pneumatic actuator, achieving in the purpose of automatic control and remote control on the butterfly valve action.
There are two types of butterfly valves mounted with the pneumatic actuator, one type is wafer type butterfly valve mounted with pneumatic actuator, the other type is flanged type butterfly valve mounted with pneumatic actutor.
There are two types of pneumatic actuators mounted with the butterfly valves, one type is single action pneumatic actuator (which is also called spring return pneumatic actuator); the other type is double action pneumatic actuator. Normally, the clients select the spring return pneumatic actuator, because this type of pneumatic actuator needs only one air supply.
