The gate valve is a shutoff valve that controls the flow of pipeline media through the vertical movement of the gate. Its core component is a wedge-shaped or parallel gate, driven by the valve stem to move up and down to achieve a full open or full closed state. This design focuses on completely cutting off the flow, providing a straight flow channel in the fully open state to minimize fluid resistance.

The most prominent feature is its full-diameter design and reliable shutoff performance. When fully opened, the gate is completely retracted into the upper part of the valve body, forming a channel consistent with the pipeline diameter, generating almost zero additional flow resistance.

The gate valve adopts a flow channel structure with the same diameter as the pipeline. When opened, the valve plate is completely separated from the medium flow path, forming a nearly unobstructed straight-through flow channel. This design significantly reduces pressure loss and is particularly suitable for large-flow conveying systems.

Effective sealing can be achieved on both sides of the gate valve plate without being restricted by the flow direction of the medium. The symmetrical sealing structure design ensures the same sealing effect when installed in either direction, providing flexibility for pipeline layouts.
