Pneumatic butterfly valves play an important role in our daily life and production. Pneumatic butterfly valves have a wide range of uses, mainly used in the drainage and gas pipelines of petroleum, chemical, jewelry, natural gas, electric power, textile, papermaking and other industries. The role of intercepting media. Let's take a look at the specific information of pneumatic butterfly valves which are classified.

     Pneumatic butterfly valve is composed of (spring return type) pneumatic actuator and butterfly valve. It is a rotary high-performance regulating or shut-off valve, equipped with electricity, pneumatic valve positioner or solenoid valve, air filter pressure reducer, limit switch ( Valve position echo device), which can realize the proportional adjustment and two-position cut-off control of the fluid medium in the process pipeline, so as to achieve the automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.

     The classification standards for pneumatic butterfly valves are: pneumatic butterfly valves, connecting flanges, wafers, lined with nitrile butadiene rubber, ethylene propylene rubber, heat-resistant ethylene propylene rubber, natural rubber, chloroprene rubber, fluorine rubber, which are more reasonable according to the chemical properties of the medium. s Choice.
