Advantages and disadvantages of globe valves
Advantages and disadvantages of globe valves
shortcoming
1. The fluid resistance is high, and a large amount of force is required for opening and closing.
2. Not suitable for media with particles, high viscosity, and easy coking.
3. Poor regulation performance.
4. The types of globe valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight through, direct current, and angular types. Globe valves are divided into packing sealed globe valves and bellows sealed globe valves according to their sealing forms.
5. The bellows sealed globe valve adopts a bellows sealed design, completely eliminating the disadvantages of aging and easy leakage of ordinary valve stem packing seals. It not only improves energy efficiency, increases production equipment safety, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment.

advantage
1. Double sealing design (bellows+packing): If the bellows fails, the valve stem packing will also be avoided;
2. Leakage and compliance with international sealing standards;
3. No fluid loss, reduce energy loss, and improve factory equipment safety;
4. Long service life, reduced maintenance frequency, and lowered operating costs;
5. The sturdy and durable bellows sealing design ensures zero leakage of the valve stem and provides maintenance free conditions. The types of globe valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight through, direct current, and angular types. Globe valves are divided into packing sealed globe valves and bellows sealed globe valves according to their sealing forms.
