The midline butterfly valve, as a component used to realize the on-off and flow control of pipeline system, has been widely used in many fields such as petroleum, chemical industry, metallurgy and hydropower. In the known butterfly valve technology, the sealing form of the sealing structure, the sealing material for rubber, ptfe and so on. Due to the limitation of structural characteristics, it is not suitable for high temperature, high pressure and corrosion resistance, anti-wear and other industries. There is a more advanced butterfly valve is the three-eccentric metal hard seal butterfly valve, the body and the valve seat are joined members, the valve seat sealing surface layer surfacing welding temperature resistant, corrosion resistant alloy material. The multi-layer soft folding sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, this kind of butterfly valve has the advantages of high temperature resistance, light operation, open and close without friction. Size: 2"～48"
