SD non-intrusive intelligent electric actuator is the execution unit in industrial automation instrument, it receives 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, chemical mine, light industry, pharmacy, gas power, building materials, transportation and city subway, water supply, sewage treatment and other industries.
Main technical parameters of SD electric actuator.
