1.Introduction of China Pneumatic Actuator Flange Butterfly Valve manufacturers

The plate of China Pneumatic Actuator Flange Butterfly Valve manufacturers can be opened and closed by rotating 90 degrees. The operation is simple and the airtightness is good. Due to the equal medium action of the disc wrench on both sides of the valve shaft, the torque direction is opposite, so the opening and closing torque is small, and good sealing can be achieved under low pressure; China Pneumatic Actuator Flange Butterfly Valve manufacturers is made of NBR and fluororubber, which is a kind of pneumatic flange soft sealing butterfly valve. Among them, the hard seal butterfly valve is a multi-layer metal hard seal, which has the advantages of elastic seal and excellent sealing performance at low temperature. Therefore, China Pneumatic Actuator Flange Butterfly Valve manufacturers is mainly used in pipelines with corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage.
