The installation and maintenance of the globe valve what should pay attention to

The types of globe valves are divided into external thread type and internal thread type according to the position of the stem thread. According to the flow direction of the medium, there are straight-through type, direct flow type and angular type. The globe valve is divided into packing seal globe valve and bellows seal globe valve according to the sealing form.

The installation and maintenance of the globe valve should pay attention to the following matters:
1:Handwheel, handle-operated shut-off valves can be installed anywhere in the pipeline
2:Handwheels, handles and weiding mechanisms are not allowed for lifting.
3:The flow direction of the medium should be consistent with the direction of the arrow shown in the valve body.
Globe valves offer the following advantages:
1:The structure is simple, and the manufacturing and maintenance are more convenient.
2:The working stroke is small, and the opening and closing time is short

3:Good sealing, Small friction force between sealing surfaces, Long Life
Globe valves have the following disadvantages:
1:The fluid resistance is high, and the force required to open and close is large
2: Not suitable for media with particles, high viscosity and easy coking

3:Poor tuning performance
