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 are designed for remote and local control of shut-off pipeline valves having a quarter-turn shut-off valve. They are used in various branches of national economy: in gas, oil, metallurgy, food industry, housing and utilities, etc.
