Triple Offset Graphite Multilevel Btterfly Valve

◆ The thriple offset multi-layer hard-sealed butterfly valve, the valve body and the valve seat are connected components, and the sealing surface layer of the valve seat is made of surfacing welding temperature-resistant and corrosion-resistant alloy material. The multi-layer soft laminated sealing ring is fixed on the valve plate.This kind of butterfly valve is easy to operate. and the opening and closing is rapid. When closing, the torque of the transmission mechanism is increased to compensate for the sealing, which improves the sealing performance of the butterfly valve and the advantages of prolonging the service life.
