The difference between gate valve and globe valve

What is the difference between a gate valve and a globe valve? There are a lot of people who don't know the difference between gate valve and globe valve. TJL introduces you to the most common difference between gate valve and globe valve.

The difference between gate valve and globe valve

1. The gate valve and the shutoff valve are different in structure. The gate valve is more complex than the stop valve and has a large height. The gate valve is shorter and higher than the shut-off valve. In particular, the open gate valve requires a high height space, which should be noted in the case of limited installation space.

2. The sealing surface of the gate valve and the shutoff valve are different.

3. The flow resistance of the gate valve and the stop valve are different. When the gate valve is fully open, the entire flow passage is straight through. At this time, the pressure loss of the medium is minimized, the flow resistance of the shut-off valve is large throughout the stroke, the imbalance force is large, and the required driving force or torque is correspondingly It is much bigger. However, it is well suited for use as a conditioning and throttling fluid.

4. The flow direction of the gate valve and the shutoff valve are different.

5. The gate valve and the stop valve have different strokes. The stroke of the gate valve is larger than that of the shut-off valve.

6. The maintenance process of China gate valve and globe valve is different. The maintenance of the gate valve is not suitable for on-site pipelines, and the valve seat and disc of most of the shut-off valves can be replaced online without removing the entire valve from the pipeline. This is where the valve and pipeline are welded together. It is very suitable.
