The Advantages Of Gate Valve

2022/11/25 10:29

Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.

Advantages of the gate valve.

1. low fluid resistance

Because the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.

2. Small opening and closing resistance

Because the gate valve opening and closing gate movement direction is perpendicular to the direction of media flow, compared with the globe valve, the gate valve opening and closing is less effort.

3. The direction of media flow is not restricted

The medium can flow from both sides of the gate valve in any direction, can achieve the purpose of use, more suitable for the flow direction of the medium may change in the pipeline.

4. Short structure length

Because the gate valve gate is placed vertically in the valve body, while the globe valve raft is placed horizontally in the valve body, so the structure length is shorter than the globe valve.

5. Good sealing performance

The sealing surface is less eroded when fully open.
