BUTTERFLY VALVE

Double Eccentric

EN 558 Series 14 (DIN 3202-F4) Double Eccentric butterfly valve. The two-axis shifted disc design reduces friction at the disc sealing area and lowers operating torque. Butterfly valves are used for isolation purposes and provide drip-tight sealing once closed (not suitable for regulation purposes).
