DURAVIS Electric Wafer Type Butterfly Valve

Description:
DURAVIS Electric Actuated Wafer Type Butterfly Valves are a rotary automatic control valves which is a combination of a wafer type butterfly valve and an electric actuator. Electric Actuated Butterfly Valves can be produced from DN 40 to DN 3000, or even above it. The BFV-W1EPA Series valves thankfully its ISO5211 standard top flange are fully compatible with DURAVIS rotary electric actuators. Preferably, the valve body can be GG-25, GGG-40 or Steel Casting. Different voltage options are available and in addition to on-off version, those valves come up with proportional models for modulating control.
