This is a high-pressure forged flanged gate valve. The valve body is a solid, one-piece forged steel block structure (without casting parting lines, and the material is dense and uniform), capable of withstanding ultra-high pressure impacts and stress changes under complex working conditions. It is a standard feature of ultra-high pressure valves. Flange connections at both ends facilitate installation, disassembly, and maintenance on high-pressure pipelines. Industrial anti-corrosion coating enhances the valve body's corrosion resistance and complies with equipment marking standards in power plants, refining, and other industries. The high-pressure forged flanged gate valve, with its forged structure's strength and sealing stability, ensures the safe flow of fluids in pipelines.

Features
Material and Manufacturing Process
The valve body is forged from F91 martensitic heat-resistant steel, free from casting defects, with high material density, capable of stably withstanding Class 950 (approximately 16MPa) ultra-high pressure impacts. High-Temperature Compatibility: F91 steel possesses excellent high-temperature strength and creep resistance, allowing for long-term operation in environments above 550℃ without significant aging or sealing failure.
Structural and Design Features
Rising Stem + Heavy-Duty Valve Body: The rising stem design allows for direct observation of the valve's opening and closing status, reducing the risk of high-pressure operation. The solid, block-shaped valve body has sufficient thickness, minimizing structural deformation under high pressure. Flange Connection: Standardized flange interfaces at both ends facilitate modular installation in industrial pipelines, eliminating the need for pipeline damage during maintenance and improving operational efficiency. Anti-Corrosion Coating: A blue epoxy + polyurethane composite coating enhances the valve body's corrosion resistance in salt spray and humid environments, extending its service life in outdoor/marine conditions.
Performance and compatibility features
Reliable sealing under ultra-high pressure; the hard-seal valve seat combined with the high-precision machining of the forged valve body results in leakage far below standard requirements under high pressure; strong compatibility with various operating conditions, including "ultra-high pressure + high temperature + corrosion", making it a core pipeline control component in power plants, refining, coal chemical and other fields.
Advantages
Ultra-high pressure withstand capability
Utilizing integral forged steel technology (solid block valve body) + Class 950 (approximately 16MPa) high pressure rating, the material's density is far superior to cast steel, enabling stable resistance to the impact of ultra-high pressure fluids and ensuring high sealing reliability.
Strong high-temperature adaptability
The valve body is made of F91 martensitic heat-resistant steel, possessing excellent high-temperature strength and creep resistance. It can operate stably for extended periods under high-temperature conditions above 550℃, with minimal risk of material aging or seal failure.
High structural reliability
Employing an upward-rising stem + flange connection design: The upward-rising stem structure facilitates direct observation of the valve's opening and closing status, reducing operational risks under high-pressure conditions; the flange connection adapts to standardized installation in industrial pipelines, eliminating the need for pipeline damage during subsequent maintenance.
Corrosion resistance and durability
The blue industrial anti-corrosion coating enhances the valve body's corrosion resistance in humid and salt spray environments. Combined with the high-temperature oxidation resistance of the F91 material, its service life is extended by more than 30% compared to ordinary carbon steel valves.
Application Scenarios
High-Temperature Steam System for Power Plants
Adapted to the main steam and reheat steam pipelines of supercritical/ultra-supercritical power plants, responsible for the on/off control of high-temperature and high-pressure steam (F91 material can withstand high steam temperatures).
01
High-Pressure Process Pipelines in Refining and Chemical Industries
Used in high-pressure units such as hydrocracking and catalytic reforming in petroleum refining plants, controlling the transportation of high-pressure oil and gas media (ultra-high pressure withstand capability adapted to process requirements).
02
High-Pressure Reactors in Coal Chemical Industries
Adapted to high-pressure syngas and methanol synthesis pipelines in coal chemical industries, resistant to both high pressure and media corrosion.
03
High-Pressure Pipelines in Marine Engineering
Used for high-pressure crude oil/natural gas transmission pipelines on offshore platforms; anti-corrosion coating + forged steel structure adapts to marine salt spray environments and high-pressure conditions.
04
Production Process
High-pressure forged flange gate valves are manufactured using a free forging + machining process. The core of this process is to process metal billets into valve bodies through forging (rather than casting), which is the standard process for high-pressure valves.
