Application
The seat sealing surface layer is deposited with a temperature-resistant and corrosion-resistant alloy material. The multi-layer soft stack sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve has high temperature resistance, light operation, no friction in opening and closing, and the seal is compensated with the increase of the torque of the transmission mechanism when closing, and the butterfly valve is improved. The sealing performance and the advantage of extending the service life.
