Pneumatic Butterfly Valve

Description

Description

Pneumatic butterfly valve is the kind of butterfly valve with pneumatic actuator. Pneumatic butterfly valve is mainly used for truncation valve, but also can be designed as regulating valve.

Pneumatic butterfly valve，using compressed air as the power source, the cylinder as the actuator, and with the help of electrical valve positioner, converter, solenoid valve and other accessories to drive the valve, to achieve switching volume or proportional adjustment, receive industrial automation control system control signals to complete the adjustment of pipeline medium flow, pressure, temperature and other process parameters. Pneumatic butterfly valve is characterized by simple control, rapid response, and intrinsically safe, do not need to take additional explosion-proof measures.

Features

1.Compact and lightweight, easy to disassemble and repair, can be installed in any location;

2.Simple structure, small operating torque, open and close quickly with only 90° turn;

3.The butterfly plate can be sprayed with coating according to the user’s medium requirements, such as nylon or PTFE;

4.Cylinder is made of aluminum alloy material, light weight, beautiful appearance;

5.The pneumatic butterfly valve connection endcan be designed into flange connection and wafer connection ;

6.Pneumatic butterfly valve is especially suitable for low pressure, large diameter pipelineuse ;

7.The connection between the disc and the valve stem is made of a pin-free structurewhich can  overcome possible internal leakage points ;
