Description
The butterfly valve is designed for use as a shut-off or control valve to control flows 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 disk by 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
The DNOVA reducer allows you to manually set the required positioning of the shut-off element by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn drives.
