The structural characteristic of the pneumatic butterfly valve is as following:
Pneumatic actuator:Center line elastic seal: The seal materials are rubber and fluoroplast. The elastic valve seat is equipped with high-precision valve plate to make sure there is no leak.The top, middle part and bottom of the valve handle is equipped with bush to support and rotate the slide and keep the minimum friction. The products weight is light, the bulk is small and the speed of opening and closing is very quick.
Three-dimension eccentric seal construction: The seal material valve seat is metal or fluoroplast. The metal seal butterfly valve has elastic seal ring valve seat and multilayer composite valve plate. The friction of the three-dimension eccentric seal construction is small as open and close. The seal performance is credible. This construction is antiwear and high-temperature resistant, has the minimum leak and the long use-life. The construction has the reasonable structure, light weight, small bulk and installing dimension, simple operation and quick open and close speed, and its development is very quick and the application is very wide.
