Bellows globe valve installation and maintenance precautions
  The bellows globe valve has the following advantages:
1. Simple structure, convenient to manufacture and maintain.
2. The working stroke is small and the opening and closing time is short.
3, good sealing, small friction between sealing surfaces, long life.
The disadvantages of the bellows stop valve are as follows:
1. The fluid resistance is large, and the force required for opening and closing is large.
2. It is not suitable for media with particles, high viscosity and easy coking.
3. The adjustment performance is poor.
The installation and maintenance of the bellows stop valve should pay attention to the following items:
1. The handwheel and handle operated shut-off valve can be installed at any position of the pipeline.
2. Handwheels, handles and aerodynamic mechanisms are not allowed to be used for lifting.
3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
