The rotary disc valve is designed for use as a shut-off or control valve for flow control in heat supply systems, water supply systems, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries. Operating principle: The valves open and close by turning the disc by 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
