D673H Pneumatic wafer butterfly valve introduction
D673H Pneumatic wafer butterfly valve adopts triple eccentric tructure design, through strict calculation, "U" type sealing ring and butterfly plate almost frictionless, solve the traditional eccentric butterfly valve in the opening and closing 0 to 10 degrees instantaneous sealing surface are still thousands of sliding friction ills, realize the butterfly plate in open the instant sealing surface, the separation, close contact with the sealing effect and prolong the service life, sealed performance is the best.
The sealing surface of D673H Pneumatic wafer butterfly valve is made of butt-welding and drilling base hard alloy, and the sealing surface is resistant to wear. The large-sized butterfly plate is made of spinning frame mechanism, featuring high strength, large flow area and small flow resistance., "On and off" is accomplished by simply turning the stem 90°. Therefore D673H Pneumatic wafer butterfly valve is widely used in the medium temperature ≤425℃ metallurgical, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage and other corrosive media pipeline, as the best device to regulate the flow and cut off the fluid.
