water butterfly valve elephant wbv3ex 3431m 1w f iso body material carbon steel disk material stainless steel aisi 304 seal metal electric actuator qt n xem a1 220v Ball Check Valve Technical data of DA double-actingButterfly valves are designed for use as shut off or regulating valves for controlling flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk by 90. The triple eccentricity design reduces friction at the disk and seat contact points, which increases the reliability and service life of the gate. In this
