SD quarter-turn electric actuator is the terminal control device of industrial process measurement and control system. It can convert the system control signal (analog signal or intermittent signal) into mechanical displacement and output torque at the same time to control the opening of the valve or control other regulating mechanisms so that the controlled medium works according to the state specified by the system.
Intelligent electric actuator is the execution unit in industrial automation instrument, itreceives from the regulator, PLC, DCS control signal from the computer, such as the completion of automatic adjustment, is indispensable to automatic control system for main equipment. It is widely used in power station, metallurgy, petroleum, chemicalmine, light industry, pharmacy, gas power, building materials, transportation and city subway, water supply, sewage treatmentand other industries.
