Feature:

Pneumatic flange butterfly valve, pneumatic flange butterfly valve. This product consists of a rubber-sealed butterfly valve and a carbon steel or stainless steel valve plate and valve stem.

It is suitable for regulating flow and intercepting medium in water supply and drainage, gas pipelines with a temperature of ≤80-120°C, such as food, chemical, petroleum, electricity, textile, papermaking, etc.

Pneumatic regulating butterfly valve is a valve (valve plate) that rotates around a fixed axis perpendicular to the channel.

It consists of a piston-type double-acting or single-acting (spring return) pneumatic actuator and a butterfly valve. It is a rotary high-performance regulating or shut-off valve.

It is equipped with an electric, gas valve positioner or solenoid valve, an air filter pressure reducer, and a limit switch (valve position feedback device). It can realize the proportional regulation and two-position cut-off control of the fluid medium in the process pipeline, thereby achieving automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.
