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 performed by turning the handle counterclockwise, closing - clockwise.
Electric quarter-turn actuators are designed for remote and local control of 0° ~ 270° rotation of a shut-off valve of such types as ball valve, etc.
Operating principle: electric actuators are mounted directly on pipeline valves. The mounting dimensions comply with the international standard ISO 05211 / DIN3337. Four microswitches are used to limit the travel of the output shaft to the end positions of the valve actuator. The actuators are designed for operation in nominal short-time mode S2.
