High performance double eccentric butterfly valve
Using a double eccentric butterfly plate structure and a composite valve seat, flexible sealing technology is applied to eliminate the effects of abrasion, plastic deformation, temperature, and pressure changes, achieving the cutoff function of bubble level sealing. It has the characteristics of bidirectional pressure bearing, bidirectional sealing, 100% complete interchangeability of parts, low torque, fire prevention, anti-static structure, etc. Its service life is over 100000 times, suitable for frequent opening and closing conditions.
