Description

Butterfly 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°. Opening is performed by turning the handle counterclockwise, closing - clockwise.

Explosion-proof actuators with explosion protection marking 1ExdIIBT4 quarter-turn actuators (type of connection to the valve - according to ISO 5211) are used for control of pipeline shut-off valves in chemical, oil, gas and power industries. The actuators are designed for remote and local control of shut-off valves. The actuator is powered from AC network with voltage 220V or 380V on 3-phase scheme with frequency 50 Hz, depending on the electric motor installed in it.
