Application
This type of butterfly valve series is a kind of sanitary valve which used to control the material transfer. It is widely used in food, beverage, pharmaceutical and chemical industry area.
Work principle
Pneumatic butterfly valve is operated remotely by actuator.
Actuator is to cover the axial movement of piston to be 90℃ rotation of valve shaft. So that the valve can be open or close to achieve the requirement of control and open/close for the pipeline system. They have three type of actuator: normally open (NO), normally closed (NC), air/air (A/A).
