Electric actuator gate valves are devices that control the flow of fluids by using an electric actuator to operate a gate or wedge that obstructs or allows passage through the valve. They come in different types, each suitable for specific applications. The common types include:
These valves feature a stem that moves in a linear upward direction when opening or closing the gate. The position of the stem provides a clear indication of the valve's status.
In contrast to rising stem gate valves, non-rising stem gate valves have a stem that does not move linearly when operating the gate. Instead, the stem rotates to open or close the valve, making them ideal for applications with limited vertical space.
Simple structure, easy to manufacture and maintain
Small working stroke and short opening and closing time
Good sealing performance, small friction between sealing surfaces and long life
In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, which is wear-resistant

Electric gate valve: An electric gate valve uses an electric motor instead of a handwheel. By utilizing electrical power, the actuator spins the stem to raise or lower the gate. This allows it to be operated remotely with no user on-site but requires electrical power on-site. These are also referred to as motorized gate valves.
A gate valve operates similar to other valves. To open the valve, turn the handwheel (A), which moves the gate (G) up or down on the stem (B) via the threads. A gate valve requires more than one 360° turn to open or close the valve fully. When the gate is lifted up, it opens the inlet to the outlet allowing an unobstructed passageway for the media to flow. When the gate is lowered, it closes and blocks the media flow.
The relationship between the gate's vertical travel and the flow rate is nonlinear for a gate valve, with the greatest changes occurring near-complete closure. When used to regulate flow, the relatively high velocity of the flow at partial opening results in gate and seat wear, which along with possible vibrations of the gate, shortens the valve's service life. Therefore, a gate valve should only be used for on/off control.
