When used as a cutoff, the sealing performance of the gate valve and the globe valve is the same, and zero leakage can be achieved. So we don't have to compare the gate valve or the globe valve, because there are still many differences between the two, the valve types are different, and it is not suitable for comparison.
The advantages of gate valves are:
1. When the valve is fully opened, the fluid resistance in the valve body channel is almost 0, and the sealing surface is less brushed and eroded by the medium.
2. It is more labor-saving to open and close.
3. The inside of the valve body is a straight-through flow channel, the medium can flow in both directions, and can be installed at any position in the pipeline without being restricted by the flow direction of the medium.
4. Compared with the globe valve, the structural length is shorter and the installation is more convenient
The disadvantages of gate valves are:
- It can only be fully opened or fully closed and used as a shut-off valve.
- When opening and closing, the travel distance of the valve plate is large. Although opening and closing saves effort, it takes a long time.
The advantages of globe valve:
- The working stroke is small and the opening and closing time is short.
- Good sealing performance, small friction between sealing surfaces and long service life.
- It can be used to adjust the flow rate.
- The fluid resistance is large, and it is more laborious to open and close.
- It is not suitable for medium with particles, high viscosity and easy coking.
- The length of the structure is large.
The gate valve is a gate with an opening and closing part. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed. It varies with the gate parameters, usually 5°, and 2°52 when the medium temperature is not high. '. To improve its manufacturability and make up for the deviation of the sealing surface angle during processing, this gate is called an elastic gate.

Therefore, it is not easy to define whether a gate valve or a globe valve is better. There are direct differences between the two types of valves. The correct installation and use of the valve can make the valve play its best role.
