The Elephant WBV1331E-2W-F butterfly valve is designed for use as shut-off or control valves 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. The valves open and close by turning the disk by 90°. Opening is done by turning the handle counterclockwise, closing - clockwise. The Elephant HGB 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 actuators.
