What is pneumatic flange butterfly valve

Flange butterfly valve, pneumatic butterfly valve with pneumatic actuator, pneumatic actuator perform relatively fast speed, and does not require workers to do, to a great extent, save the human resources and time, the main advantage of the pneumatic flange butterfly valve, simple structure, small volume light weight, low cost, pneumatic butterfly valves this characteristic is especially significant, installed in the upper air tunnel, through two five-way solenoid valve control is easy to operate, also can adjust flow medium.

Fluid resistance is small, large diameter pneumatic disc 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, disc valve sealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for soft hard cascading metal hard seal butterfly valves with metal sealing and elastic sealing heavy advantage, no matter under the condition of low temperature all have good sealing performance.
