High pressure forged steel globe valve

J41W-160PHigh pressure forged steel globe valveSummary of
The opening and closing components of the globe valve are plug shaped valve discs, with a flat or conical sealing surface. The valve disc moves linearly along the centerline of the valve seat. The movement form of valve stem, commonly known as concealed stem, can also be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media through lifting and rotating stem. Therefore, this type of shut-off valve is very suitable for use as a cut-off, regulating, and throttling valve. Due to the relatively short opening or closing stroke of the valve stem and its highly reliable shut-off function, as well as the proportional relationship between the change in the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow.

Valves play an important role in cutting off and throttling the medium in the pipeline they are located in. As an extremely important cut-off valve, globe valves seal by applying torque to the valve stem, which exerts pressure on the valve disc in the axial direction, making the sealing surface of the valve disc tightly fit the sealing surface of the valve seat, preventing the medium from leaking along the gaps between the sealing surfaces.

The sealing pair of the globe valve consists of the sealing surface of the valve disc and the sealing surface of the valve seat. The valve stem drives the valve disc to move vertically along the centerline of the valve seat. The opening height of the globe valve is relatively small during the opening and closing process, making it easy to adjust the flow rate, and easy to manufacture and maintain, with a wide range of pressure applications.

Compared with another commonly used shut-off valve in industrial production, the shut-off valve is structurally simpler and easier to manufacture and maintain. In terms of service life, the sealing surface of the globe valve is not easily worn or scratched. During the valve opening and closing process, there is no relative sliding between the valve disc and the sealing surface of the seat, so the wear and scratches on the sealing surface are relatively small, which improves the service life of the sealing pair. The globe valve has a small valve disc stroke and a relatively small valve height during the fully closed process. The disadvantage of globe valves is that they have a large opening and closing torque and are difficult to achieve rapid opening and closing. Due to the tortuous flow path inside the valve body, the fluid flow resistance is high, resulting in significant loss of fluid dynamics in the pipeline.
