What is an electric valve actuator?

Electric valve actuators are devices powered by electricity to move or control a valve. Unlike pneumatic actuators, which depend on compressed air (and thus, are susceptible to pressure fluctuations), electric actuators rely on electricity, offering more consistent and precise control.

How does a valve motor work?

The motor’s power rating (typically expressed in HP or kW) determines the actuator’s ability to handle different valve sizes and heavy load. The gearbox transfers the motion from the motor to the valve, converting high-speed, low-torque motor output into low-speed, high-torque motion required to operate the valve.

How does a rotary valve actuator work?

As its name suggests, a rotary valve actuator produces rotational motion that turns the valve stem (typically by a specific angle), either opening or closing the valve. Instead of the thrust force linear actuators rely on, rotary actuators require torque output.

How does a feedback valve work?

The feedback mechanism, often utilizing sensors, keeps track of the valve’s position as it moves. It compares the actuator’s position with the control signal sent to it and provides real-time updates back to the control unit to ensure the valve is in the correct position.
