The advantages and disadvantages of the globe valve and installation precautions
The globe valve has the following advantages:
The globe valve has the following advantages:
The shut-off valve has a simple structure and is more convenient to manufacture and maintain.
The stop valve has a small working stroke and short opening and closing time.
The shut-off valve has good sealing performance, small friction between the sealing surfaces, and long life.
The disadvantages of the globe valve are as follows:
The stop valve has a small working stroke and short opening and closing time.
The shut-off valve has good sealing performance, small friction between the sealing surfaces, and long life.
The disadvantages of the globe valve are as follows:
The shut-off valve has high fluid resistance and requires a large force when opening and closing.
The stop valve is not suitable for the medium with particles, high viscosity and easy to coke.
The shut-off valve has poor regulation performance.
The types of globe valves are classified into external thread globe valves and internal thread globe valves according to the position of the stem thread. According to the flow direction of the medium, there are straight-through stop valves, direct-flow stop valves and angle stop valves. The stop valve is divided into sealing form, there are packing sealing stop valve and bellows sealing stop valve.

The installation and maintenance of the globe valve should pay attention to the following items:
The stop valve operated by hand wheel and handle can be installed at any position of the pipeline.
Handwheels, handles and dynamic mechanisms are not allowed to be used for lifting.
The flow direction of the medium should be consistent with the arrow direction shown on the valve body.
