The SD series electric actuator are the terminal control devices of automatic regulation systems.They can receive 4-20mA analog signals output by regulators or computers,as well as intermittent contact control signals.Through outputting torque/force,they drive the regulating mechanism to complete automatic regulation.At the same time,they support the"manual-automatic"switching function through the operator,and in the manual mode,the actuators can be remotely controlling various valves valves with a 90°rotation angle,such as butterfly valves,air aoors,stop valves,and baffle valves.
