Pneumatic flange butterfly valve, butterfly valve with pneumatic actuator - pneumatic actuator execution speed is relatively fast, and does not require workers to do it themselves, to a large extent, saving human resources as well as time - pneumatic flange butterfly valve's main advantages, simple structure, small size and light weight, low cost, pneumatic disc valve the characteristics of the particularly significant, installed in the high altitude cul-de-sac, after the two two-position five-way solenoid valve control is convenient to operate and can also regulate the Flow media. Fluid resistance is small, medium and large caliber pneumatic disc valves are fully open when the effective circulation area is large, open and close quickly and labor-saving, butterfly trigger can be completed by rotating the 90 angle of opening and closing, due to the rotating axle on both sides of the disc plate hand media force is close to equal, and the torque generated by the direction of the opposite direction, and thus open and close the torque is small, low-pressure can be achieved under good sealing, disc valve sealing materials are butyl rubber, Viton® rubber, food rubber, lined with PTFE, the sealing Good sealing performance, which hard seal disc valve for the soft and hard laminated metal sheet with metal hard seal and elastic seal of the heavy advantages, no matter in the case of low temperature have excellent sealing performance.
