Double Offset Butterfly Valve
Double offset butterfly valve manufacturersare further improved on the basis of single eccentric butterfly valves and are widely used. Its structure is characterized by the deviation from the center of butterfly plate and center of body at the stem axis. The double eccentricity effect makes the disc rapidly disengage from the seat after the valve is opened, greatly eliminating unnecessary over-extrusion and scraping of disc and seat, reducing the opening resistance, reducing wear and improving the seat life.
The sharp reduction of scraping also enables the double eccentric butterfly valve to use the metal seat, which improves the application of butterfly valve in the field of high temperature. the While ZhengFeng properly solved the problem of large leakage volume, our double eccentric butterfly valves can provide rubber sealing seats and metal sealing seats according to customer requirements, both of which can achieve the same requirement of two-way pressure.
