A forged steel globe valve is a valve made from forged steel, featuring high strength, corrosion resistance, good sealing, ability to withstand high temperatures and pressures, and a long service life. It is widely used in industries such as oil, chemicals, and power, primarily for cutting off or connecting media in pipelines, and is generally not used for regulating flow.

Definition and Working Principle

The closure part (valve disc) of the forged steel stop valve moves along the centerline of the valve seat, and the change in the valve seat orifice is proportional to the stroke of the valve disc. Its operating principle is to control the fluid flow by rotating the valve stem to lift or lower the valve disc. When the valve disc is open, the fluid can flow smoothly through the valve body; when it is closed, the fluid flow is blocked. Due to the metal-to-metal sealing structure between the valve disc and the valve seat, it has good sealing performance and can effectively prevent fluid leakage.

Structure and Classification

Forged steel check valves are typically composed of components such as the valve body, cover, stem, disc, and seat. Depending on their structural characteristics and application scenarios, forged steel check valves can be categorized into various types, including straight-through, angle, direct flow, and plunger designs. The straight-through check valve is suitable for general pipeline systems; the angle check valve is used when a change in fluid direction is required; the direct flow check valve is suitable for situations with low flow resistance requirements; and the plunger check valve is used for high-pressure sealing applications.

Application Scenarios and Advantages

Forged steel stop valves are suitable for pipelines or installations handling high-temperature, high-pressure media, such as those in power plants and petrochemical systems with high-temperature, high-pressure pipelines. They can also be used for a variety of media including water, steam, and oil products. Their advantages include:

‌Good sealing property: Utilizes a metal-to-metal sealing structure, offering reliable sealing performance and effectively preventing fluid leakage.‌

High-Temperature and High-Pressure Resistance: Made of forged steel, it can withstand high temperatures and pressures.

Simple structure: Easy to install and maintain, suitable for various industrial application scenarios.
