The globe valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. 

The advantages of globe valves are mainly reflected in the following aspects:

1. Superior sealing performance

The globe valve adopts a pressure-tightening sealing structure, which can achieve better sealing effect under the action of medium pressure. As the pressure increases, the sealing performance is more reliable, especially suitable for high-pressure environments. 

In addition, its sealing surface is usually welded with wear-resistant and high-temperature resistant materials, such as Stellite cobalt-based cemented carbide or CR13. The selection of these materials enables the valve to adapt to various harsh working conditions and ensure the wear resistance, high temperature resistance and long life of the sealing surface. 

2. Compact structure and good opening and closing performance

The globe valve has a compact structural design and excellent opening and closing performance. The opening or closing stroke of the valve stem is relatively short, the opening and closing time is short, and the operation is easy. At the same time, the Y-shaped inner cavity of the valve can realize the rapid flow of fluid, reduce the flow resistance, and improve the control effect of the fluid.

3. Strong applicability

The globe valves are widely used in many industrial fields such as petroleum, chemical industry, metallurgy, and electric power. It can control the flow of various media, including high-temperature and high-pressure steam, corrosive media, etc., to ensure the safe operation of the pipeline system and the continuity and stability of the production process.

4. Flexible operation and convenient maintenance

The globe valve is flexible to operate, and the valve core rotates easily, so that the flow rate can be adjusted accurately and quickly when controlling the fluid. At the same time, the maintenance of the valve is relatively convenient, which can reduce the downtime of the equipment and improve work efficiency.

5. Long life

Since the sealing surface of the globe valve is made of wear-resistant and high-temperature resistant materials, and the structural design is reasonable, its service life is relatively long and can meet the needs of long-term stable operation.

6. Conclusion

In summary, the globe valve has been widely used in modern industrial systems with its superior sealing performance, compact structure, good opening and closing performance, wide applicability, flexible operation and long life.
