Speaking of the use of electric actuators, in fact, is to convert the motor rotary motion into the operation of their own (linear operation / rotary operation) to achieve the electric actuator to achieve the operation. And has a remote control function, local control functions, can be electric operation can also be manually operated.
The basic actuator is used to drive the valve to the fully open or fully closed position. Actuators for control valves can precisely position the valve anywhere. Although most actuators are used for on-off valves, today's actuators are designed to go beyond the simple switching functions of position sensing, torque sensing, electrode protection, logic control, digital communication modules And PID control module, etc., and these devices are all installed in a compact housing.
