Concentric Butterfly Valve
In the well-known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of structural characteristics, it is not suitable for industries such as high-temperature resistance, high-pressure resistance, corrosion resistance, and wear resistance. An existing more advanced reliable butterfly valve is a triple eccentric metal hard-sealed butterfly valve, the valve body and the valve seat are connected components, and the sealing surface layer of the valve seat is welded with temperature-resistant and corrosion-resistant alloy materials. The multi-layer soft laminated sealing ring is fixed on the butterfly valve concentric plate. Compared with the traditional butterfly valve, our concentric butterfly valve for sale has high-temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism i...
