Pneumatic butterfly valves are classified into pneumatic flanged butterfly valves, pneumatic regulating butterfly valves, pneumatic wafer butterfly valves, pneumatic rubber-lined butterfly valves, pneumatic fluorine-lined butterfly valves, etc. Let Zhejiang Shuangzhong Automatic Control Valve show you the action points of different pneumatic butterfly valves.
Pneumatic Flanged Butterfly Valve, Pneumatic Flanged Butterfly Valve This product is composed of a rubber-sealed butterfly valve and a carbon steel or stainless steel valve plate and valve stem. It is suitable for water supply and drainage and gas pipelines with temperatures ≤80~℃, such as food, chemical, petroleum, electric power, light textile, papermaking, etc., to adjust the flow and intercept the medium.
A 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 high-performance rotary valve. Adjusting or shut-off valves, equipped with electricity, air valve positioner or solenoid valve, air filter pressure reducer, limit switch (valve position echo device), can realize proportional adjustment and two-position adjustment of the fluid medium in the processing pipeline Cut off control, so as to achieve automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.
