How it works
Electric quarter-turn actuator
Construction
Parts and materials
Electric quarter-turn actuators are designed for remote and local control of shut-off pipeline valves having a quarter-turn shut-off valve. They are used in various branches of national economy: in gas, oil, metallurgy, food industry, housing and communal services, etc. The actuators are installed directly on pipeline valves. The mounting dimensions comply with the international standard ISO 5211. Four microswitches are used to limit the output shaft travel to the end positions of the valve actuator. The actuators are designed for operation in repeated-short-time mode S2 with a switching time of 10 minutes.
