r, type electric actuator is the execution unit in the type electric unit combination instrument. It receives the control signal from the upper instrument and automatically controls the actuator to complete the adjustment. Task, widely used in power stations, chemical industry, petroleum, metallurgy, building materials, water treatment, heating, light industry and other industries.
r, type electric actuator, equipped with corresponding electric operation It can complete the manual-to-automatic switching of the adjustment system without disturbance, and the remote manual operation of the actuator.
