Pneumatic concentric wafer butterfly valve introduction:
Pneumatic concentric wafer butterfly valve is wafer type with double or single acting pneumatic actuator,simple structure, small volume, light weight, low cost,Pneumatic concentric wafer butterfly valve fully open the effective flow area is larger, easy opening and closing fast, disc pull rotation Angle of 90 to complete opening and closing, due to the rotation axis disc plate hand medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing,Pneumatic concentric wafer butterfly valvesealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good.
Pneumatic concentric wafer butterfly valve is  widely used in building materials, metallurgy, mining, power and other production process medium temperature ≤100℃ nominal pressure of 0.1Mpa on the pipeline, for connecting, opening and closing or regulating medium quality.
