In this article, we will introduce the advantage, disadvantage and installation tips of globe valve.

Globe valve has the following merits:

1. Easy to manufacture and be maintained due to its simple structure.                  

2. Short opening and closing time with small working stroke.

3. The globe valve owns a good sealing performance.

4. The small frictional force between sealing surface leads to longer service life of globe valve.

Globe valve has the following disadvantage:
1. The fluid resistance of globe valve is big, which requires larger force during operation.

2. Globe valve is not suitable coking medium with larger particles and viscosity.
3. Globe valve has poor regulation performance.

Types of globe valve:
1. According to the position of the valve stem thread, we have external thread type globe valve and internal thread type globe valve.

2. According to the flow direction of medium, we have straight-through globe valve, straight-flow globe valve and angle type globe valve.

3. In terms of the sealing form, globe valve has packing seal globe valve and bellows seal globe valve.

The following aspects should be paid attention to when globe valve is installed and maintained.
1. Globe valve with manual operation can be installed in any position.
2. The hand wheel and handle do not allow for lifting.
3. The flow direction of medium should be consistent with the direction arrow on the valve body.
