An electric gate valve is a valve that uses an electric actuator to drive the gate disc up and down, achieving automated control of the medium in the pipeline. Its simple structure and excellent sealing performance make it suitable for applications with high sealing requirements.
Structural Features of Electric Gate Valve:
- Gate Structure: The gate of an electric gate valve is typically wedge-shaped or parallel. It is driven by an electric actuator to raise and lower the gate, opening and closing the pipeline. A sealing surface is formed between the gate and the valve seat, ensuring the valve's tightness when closed.
- Electric Actuator: The electric actuator consists of a motor, a reducer, and a stroke control mechanism. It receives control signals to raise and lower the gate, controlling the valve's opening and closing.
- Excellent Sealing Performance: The gate and seat of an electric gate valve form a metal-to-metal sealing surface, providing excellent sealing performance and making it suitable for applications requiring high sealing requirements.
- Low Flow Resistance: When fully open, the gate does not obstruct the pipeline's inner diameter, resulting in low flow resistance and suitable for controlling high-flow media.
