SD series electric actuator is the ultimate control device for industrial process measurement and control system. It can convert the control signal of the system into the displacement of the output part (cross displacement, multi-angle displacement or linear displacement) to output torque or force to control the valve The position of the inner shut-off piece or other adjustment mechanism makes the controlled medium work according to the state specified by the system.
The electric operator can complete the conversion of the electric actuator from “manual” to “automatic” working state. When the electric operator is placed in the "manual" position, the electric actuator can be remotely operated with the operator.
SD series electric actuators have three types of products: quarter-turn, multi-turn and linear-turn.
Angular stroke electric actuators are used to drive 90° angle valves such as butterfly valves, ball valves, flap valves, dampers, plug valves, flapper valves, etc.
Multi-turn electric actuators are used to drive gate valves and other regulating valves that require multiple turns of rotation.
The linear-turn electric actuator is used to drive the control valve that needs linear displacement, such as single-seat and double-seat control valve, sleeve valve and so on.
SD series electric actuators are safe and reliable, with many varieties and specifications, high precision, complete functions, light weight, convenient installation, debugging, operation and maintenance. They are widely used in energy, metallurgy, petroleum, light industry, chemical industry, building materials and other industries, which has an important role in process measurement and control systems.
