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 concentric butterfly valveis 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 salehas high-temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism increases to compensate for the sealing, which improves the concentric flanged butterfly valve. The advantages of sealing performance and extended service life. UTOMST, as one ofconcentric butterfly valve suppliers, has its own concentric butterfly valve factory.
