introduction
The forged globe valve is a key fluid control component made of high-strength forged steel material. It consists of the valve body, valve cover, valve core, valve seat, sealing surface, handwheel, and other components, and is connected to the pipeline system by thread, welding, or flange. The forged steel stop valve is widely used in many industrial fields such as petroleum, chemical, electric power, steel, papermaking, medicine, food, etc. for its excellent high-pressure resistance, corrosion resistance, and sealing performance. It is used to cut off or regulate the fluid medium in the pipeline.
feature
Excellent high-pressure resistance
The forged globe valve is made of high-strength forged steel material and can withstand extremely high pressure. Its design pressure range is wide, from PN1.0 to PN64 (ANSI CLASS 150-4500), ensuring the stable operation of the valve in various high-pressure environments.
Excellent sealing performance
The valve core and valve seat sealing surface are precision machined and specially treated to ensure a long-term sealing effect. The integrated seat design enhances the stability of the sealing surface and reduces the risk of leakage. The sealing performance of the forged steel stop valve can reach the zero leakage standard, and it can maintain a stable sealing effect under high temperature, high pressure, and corrosive media environments.
Diverse end connections and drive modes
The forged steel stop valve provides a variety of end connection methods, including SW (threaded welding end), NPT (threaded end), and BW (butt welding end) to meet the connection requirements of different pipeline systems. At the same time, it also supports a variety of drive methods, such as manual, pneumatic, electric, etc., to meet the operation requirements in different scenarios.
• SW (threaded welding end): suitable for pipeline systems that require high-strength connection and long-term stability requirements, such as oil and gas transmission pipelines.
• NPT (threaded end): commonly used in low-pressure and small-diameter pipeline systems, easy to install and disassemble quickly, suitable for laboratories, small equipment, and other scenarios.
• BW (butt welding end): suitable for high-pressure, large-diameter, and high-temperature pipeline systems, such as power station boilers, oil refining units, etc.
In terms of drive mode:
• Manual: suitable for occasions that require frequent operation and low pressure, such as small factories, laboratories, etc.
• Pneumatic: suitable for occasions that require remote control and a high degree of automation, such as large chemical plants, petrochemical plants, etc.
• Electric: suitable for occasions that require precise control and monitoring, such as power stations, steel plants, etc.
