Stainless Steel Sanitary Three-piece Pneumatic Butterfly Control Valve

Pneumatic butterfly valve is consist of manual butterfly valve and a pneumatic actuator . The valve is consist of four parts: handle, butterfly disc, sealing ring and valve flange.

The pneumatic butterfly valvesare mechanical polished as standard, with a smooth surface to ensure cleanliness and no areas to create potential contamination. Quick-operation makes the valve open and maintenance safe and easy, reducing process downtime.

Stainless Steel Sanitary Three-piece Pneumatic Butterfly Control Valve

The pneumatic butterfly valve is controlled by compressed air through an aluminum piston or stainless steel piston . The piston controls the disc to work at 90 degree to open or close the valve. Pneumatic actuators can be disassembled and serviced. The pneumatic actuator has large torque and is easy to install and operate.


Working Principles

未标题-1

The pneumatic actuator with a single spring return design or double air acting design. The compressed air pushes the core piston in the pneumatic actuator to compress downward to drive the rotary head so that the rotary head rotate 90 degree, and the square core is connected with the pneumatic actuator and valve disc to drive the valve to be open and close. The valve is opened or closed according to the flow of the control medium in the pipeline
