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.
Operating principle: The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
Electric quarter-turn actuators of explosion-proof version are designed for remote and local control of the rotation of the shut-off body by 0° ~ 270° of such types as ball valve, etc. They are widely used in various branches of national economy: in gas, oil, metallurgical, food industry, housing and communal services, etc. Suitable for use in industrial explosion hazardous areas.
