Metal Hard Sealed Butterfly Valve
The metal hard-seal butterfly valve has an eccentric metal sealing structure, which has high sealing performance and corrosion resistance. The sealing forms can be divided into: metal-to-metal sealing, replaceable metal sealing ring-to-metal sealing, stainless steel plate and graphite composite plate sealing ring pairing Metal seal. Classified according to the number and type of eccentricity, mainly including double eccentric, triple eccentric and quadruple eccentric butterfly valves.
