The SD series intelligent electric actuators include three types of products: rotary, multi-turn, and linear actuators. The rotary electric actuator B+RS250/F40H is used to drive valves with a 90° rotation, such as butterfly valves, ball valves, louver valves, dampers, plug valves, and baffle valves. The multi-turn electric actuators are used to drive gate valves and other control valves that require multiple turns. The linear electric actuators are used to drive single- and double-seated control valves, sleeve valves, high-temperature and high-pressure valves, feedwater, and desuperheated water control valves that require linear displacement.

Angular Travel Electric Actuator B+RS250/K40HThis makes the entire gearbox not only have higher mechanical transmission efficiency but also features mechanical self-locking. Using lithium-based grease for long-term transmission lubrication ensures maintenance-free operation during major overhauls. The cam adjustment is extremely convenient. You only need a screwdriver to adjust the adjustment wheel to rotate the corresponding cam, allowing you to set the cam to the desired position. Use a screwdriver to lift the cam and lock it in this position (after the electrical limit, rotate the actuator. This range is adjusted at the factory, and unless the C mechanism is removed and the cam needs to be readjusted, generally do not adjust it casually).
