Sanitary Butterfly Valve

Work Principle

This kind of valve can be handled by manual an electric actuator, and also can be handled by a pneumatic actuator.

Electric actuator or pneumatic actuator covert 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 (AVA).

Muti-position handle regulates the valve by 15 ° in its open or close 12 seats achiening control of medium flow purpose;

Pulling handle regulates the valve through four multi-function positioning, in its open or close four position,also achieves control of medium flow purpose.
