Stainless steel pneumatic clamp butterfly valve

The series of sanitary butterfly valve is pneumatically or manually operated,widely used in food,beverage,brewing dairy and biological engineering industries,with an intended purpose of controlling and regulating medium flow in pipelines

Working principle

The valve can be manually operated via a handle,or remotely controlled by an electric or pneumatic actuator.

The electric or pneumatic actuator converts the axial movement of piston to the rotation of shaft.So that the valve can be open or close and thus control the pipeline system.There are three types of actuator:normally open(NO),normally closed(NC),ais/air(A/A).

Via a multi-position duckbill handle,the valve can be lockable in 12 positions by 15°,achieving the purpose of medium flow controlling.

Alternatively ,to control the medium flow,one can also use a pulling handle which is able to lock the valve through fourmulti-function positions.
