Flanged Hard-Seal Gate Valve
Flanged Hard-Seal Gate Valve
Metal Seated Gate Valve for High Pressure & Temperature | Flanged Gate Valve Supplier
TheFlanged Hard Seal Gate Valveis a heavy-dutyindustrial valvedesigned for reliable shut-off in high-pressure and high-temperature pipeline systems. Featuring a metal-to-metal sealing structure, this valve ensures excellent durability, wear resistance, and long service life in demanding environments.
With a full bore design and flanged connection, it provides low flow resistance and stable sealing performance, making it ideal for water, oil, gas, steam, and industrial fluid control systems.
Standards & Certifications
Ourgate valvesare manufactured in compliance with international standards:
· Design Standard: API 600 / GB/T 12234
· Face to Face: GB/T 12221 / EN 558
· Flange Standard: ANSI B16.5 / DIN / BS
· Test & Inspection: API 598 / GB/T 13927
Product Features and Advantages
· Pressure and wear resistant, adaptable to harsh working conditions : The metal-to-metal sealing structure is wear resistant, high temperature resistant, and high pressure resistant, making it suitable for oil, gas, steam, corrosive media, etc.
· Long service life and reliable sealing : Even after long-term operation, the metal sealing surface wears slowly and can still maintain good sealing and pressure resistance.
· Wide range of pipe diameters and pressure ratings : capable of producing pipes from small diameters to large diameters, and multiple pressure ratings (PN/Class) to meet various industrial design requirements.
· Compatible with a variety of materials and standards : carbon steel, stainless steel, alloy steel, ductile iron and other materials are available, and it supports DIN / ANSI / API / GB and other standards.
Size Specifications and Standards
· A wide range of specifications are available, from small DN 50–100 to large DN 600+, all customizable.
· Pressure ratings cover PN10 / PN16 / PN25 / higher (depending on material and structural design).
· Flange connections meet international standards such as ANSI, DIN, BS, and API , and are compatible with international projects.
Functions and Applications
Hard-seal gate valves are mainly used in: oil and gas pipelines, petrochemical plants, high-pressure steam systems, industrial chemical pipelines, high-temperature and high-pressure systems, power plant steam pipelines, heavy industrial conveying systems, and other scenarios. They are particularly suitable for systems requiring high pressure, high temperature, wear resistance, corrosion resistance, and long-term stable operation.
