Flanged Hard-Seal Gate Valve

Flanged Hard-Seal Gate Valve
Metal Seated Gate Valve for High Pressure & Temperature Flanged Gate Valve
Supplier
 
The Flanged Hard Seal Gate Valve is a heavy-duty industrial valve designed
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
 
Our gate valves are 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.
