In the industrial sector, valves serve as crucial control elements in piping systems, with their performance and reliability directly impacting the operational efficiency and safety of the entire system. Forged steel globe valves, as one of the many types of valves, have been widely applied in numerous industries due to their high strength, corrosion resistance, and excellent sealing capabilities. This article will provide a detailed introduction to the structure, working principle, performance advantages, application fields, maintenance, and other aspects of forged steel globe valves, aiming to provide a reference for professionals in related industries.
Forged steel globe valves are mainly composed of a valve body, valve cover, valve stem, valve disc, and valve seat. These components are typically made of forged steel, offering high strength and corrosion resistance.
Valve Body: The valve body is the main part of the globe valve, carrying the pressure of the fluid and connecting with the piping system. Forged steel valve bodies have high strength and excellent mechanical properties, capable of withstanding high temperatures and pressures.
Valve Cover: The valve cover is used to fix the valve stem and seal the interior of the valve body. It is usually connected to the valve body with bolts for easy disassembly and maintenance.
Valve Stem: The valve stem connects the valve disc to the actuator. By rotating or lifting the valve stem, the opening and closing of the valve disc can be controlled.
Valve Disc: The valve disc is a key component of the globe valve, moving along the centerline of the valve seat to control the flow of fluid by changing the size of the valve seat orifice.
Valve Seat: The valve seat mates with the valve disc to form a sealing surface, ensuring that fluid does not leak when the valve disc is closed.
The working principle of forged steel globe valves involves rotating the valve stem to move the valve disc up and down, thereby controlling the flow of fluid. When the valve disc is in the open position, fluid can flow smoothly through the valve body; when the valve disc is closed, fluid flow is cut off.
Opening Process: Rotate the valve stem to gradually lift the valve disc, increasing the size of the valve seat orifice and allowing fluid to flow smoothly.
Closing Process: Rotate the valve stem to gradually lower the valve disc, reducing the size of the valve seat orifice until it is completely closed, cutting off fluid flow.
Due to the metal-to-metal sealing structure between the valve disc and valve seat, forged steel globe valves offer excellent sealing performance and can effectively prevent fluid leakage.
High Strength: Forged steel globe valves are made of forged steel, which has high strength and toughness, capable of withstanding high temperatures and pressures.
Corrosion Resistance: Forged steel has good corrosion resistance, suitable for transporting and controlling various corrosive media.
Excellent Sealing Performance: The metal-to-metal sealing structure ensures reliable sealing and can effectively prevent fluid leakage.
High Temperature and Pressure Resistance: Due to their forged steel construction, forged steel globe valves can withstand high temperatures and pressures, suitable for high-temperature and high-pressure conditions.
Low Fluid Resistance: The internal flow path is designed reasonably, with minimal resistance to fluid flow through the valve, ensuring smooth fluid flow.
Long Service Life: With high corrosion resistance and mechanical strength, forged steel globe valves can operate for a long time in harsh working environments.
Due to their excellent performance and wide range of applications, forged steel globe valves play an important role in multiple industries, including oil, chemicals, power, environmental protection, water conservancy, heating, water supply and drainage, industrial machinery, and more.

Based on structural characteristics and application scenarios, forged steel globe valves can be classified into various types, such as straight-through globe valves, angle globe valves, straight-flow globe valves, and plunger-type globe valves.
Straight-Through Globe Valves: Fluid flows straight through the valve, suitable for general piping systems. They have a simple structure and are easy to install and maintain.
Angle Globe Valves: Fluid changes direction once through the valve, with less pressure drop compared to conventional globe valves. Suitable for situations requiring fluid direction changes.
Straight-Flow Globe Valves: The flow path of the valve body is inclined to the main flow path, with minimal disruption to the flow state and pressure loss through the valve. Suitable for situations with low flow resistance requirements.
Plunger-Type Globe Valves: The valve disc and valve seat are designed based on plunger principles, suitable for high-pressure sealing requirements. They offer excellent sealing performance and can withstand high pressures.
To ensure the normal operation and extended service life of forged steel globe valves, regular maintenance and servicing are required.
Regular Inspection: Regularly inspect the sealing performance and opening and closing flexibility of the valve to ensure its proper functioning. Address any abnormalities promptly.
Cleaning and Servicing: Regularly clean the exterior and internal flow path of the valve to prevent dust and debris accumulation, which may affect valve operation. Use soft cloths or brushes for cleaning, avoiding metal tools that may scratch the valve body surface.
Lubrication Maintenance: Regularly add lubricant to the rotating parts of the valve to reduce wear and extend service life. Use appropriate lubricants and avoid excessive lubrication that may cause leakage.
Replacement of Sealing Elements: If sealing elements are worn or damaged, replace them promptly to ensure the valve's sealing performance. Follow the manufacturer's instructions for replacement to ensure correct installation.
Rust Prevention: For valves that have not been used for a long time, take measures to prevent rust. Apply rust-preventive oil or wrap with rust-preventive paper.
Professional Training: Provide professional training for operators to familiarize them with the valve's structure, working principle, and operation methods, improving operating skills and safety awareness.
When selecting forged steel globe valves, several factors need to be considered to ensure that the selected valve meets the actual working conditions.
Media Characteristics: Identify the type of media (e.g., gas, liquid, steam) and its properties (e.g., corrosion, temperature, pressure) in the pipeline. These factors will directly affect the material selection and sealing performance of the valve.
Temperature and Pressure: Determine the working temperature and pressure range of the pipeline to select a valve with corresponding pressure and temperature resistance. Forged steel globe valves are generally suitable for high-temperature and high-pressure environments, but specific models need to be determined based on actual requirements.
Flow Requirements: Based on the flow requirements of the piping system, select the appropriate valve diameter and flow characteristics. An excessively large or small diameter will affect fluid flow efficiency and valve control effectiveness.
Sealing Performance: Pay attention to the sealing surface material and sealing structure of the valve to ensure that the valve can effectively prevent media leakage when closed. Forged steel globe valves typically use high-quality sealing materials and advanced sealing technology to ensure good sealing performance.
Material Selection: Choose appropriate materials for the valve body, valve disc, and valve seat based on media characteristics and working conditions. Forged steel has good strength and corrosion resistance, suitable for various working environments. Consider using other special materials to meet specific requirements.
