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 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. It is suitable for ball valves, butterfly valves, valves with a 90° swing angle as well as for controlling air dampers.
