Product Detail
The electric actuator receives standard control signals (typically 4–20 mA DC electrical signal) and converts them into linear displacement.
It drives the valve stem to move up and down, which simultaneously lifts or lowers the upper and lower double plugs fixed on the stem.
By changing the flow area between plugs and seats, the valve accurately adjusts the flow rate, pressure, temperature or liquid level of the medium.
Due to the double‑seat structure, the fluid pressure acts on both plugs in opposite directions, offsetting the unbalanced force. This enables the valve to work stably under large pressure difference and high‑flow conditions.
Combined with sensors and control system, it realizes automatic closed‑loop regulation to maintain stable working conditions.
