Description
The WBV1331E-2W-F butterfly valve is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk by 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
The HAM gearbox allows manual setting of the required positioning of the shut-off body by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn actuators.
