Electric Actuators
Electric actuators operate a valve from the mains or a control signal, without a compressed air line. They suit plants where air is not available, where the valve is far from the control room, or where the valve position has to be tracked continuously.
Both on/off and modulating versions are available; the modulating unit follows a 4–20 mA or 0–10 V signal and reports its position back to the control system.
