The electric flange hard sealing butterfly valve is a three eccentric structure, metal sealed butterfly valve, which adopts the electric actuator as the driving device, double flange connection, pn0.6-pn6.4mpa, dn50-dn2000. Material: 2507, 2205 duplex steel, WCB carbon steel, SS304, SS316, SS316L stainless steel. According to the requirements, one-way pressure or two-way pressure (positive and negative two-way pressure) can be designed. According to the process control requirements, d943y electric flange hard seal butterfly valve can be adjustable electric, switch electric, integral electric and intelligent electric. It can be controlled remotely, centrally and on-site, and realize computer automatic control.

D943y electric flange hard sealing butterfly valve, the valve body and valve seat are connected components, the sealing surface of the valve seat is overlaid with high-temperature, scouring and corrosion-resistant cemented carbide materials (Stellite), and the valve plate sealing ring can be multi-level sealing materials or integral metal sealing materials, which are fixed on the butterfly plate through fasteners. The butterfly valve has the advantages of high temperature resistance, adjustable, light operation, non friction opening and closing, compensatory sealing, improved sealing performance and prolonged service life of the valve.
