GOST Metal Seated Gate Valve – China Manufacturer & Supplier

Premium Quality GOST Metal Seated Gate Valves from China

As a professional China GOST Metal Seated Gate Valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance metal seated gate valves that fully comply with Russian GOST standards. Our GOST metal seated gate valves are engineered to deliver reliable shut-off performance in the most demanding industrial environments—where high temperatures, high pressures, and abrasive media challenge the limits of resilient seated valves.

Manufactured in strict accordance with GOST 5762-2002 (design standard for steel gate valves), GOST 12815-80 (flange connection standard), and GOST 356-80 (pressure-temperature rating and testing standard), our metal seated gate valves are available in a wide range of sizes from DN50 to DN1000, with pressure ratings covering PN10, PN16, PN25, and PN40. Whether you require rising stem (OS&Y) or non-rising stem configurations, our product line offers flexible solutions tailored to your specific pipeline needs.

Why Choose GOST Metal Seated Gate Valve?

GOST metal seated gate valves utilize metal-to-metal sealing between the gate and seat surfaces, creating a durable and reliable seal that outperforms elastomer-based alternatives in harsh service conditions. This design makes them the preferred choice for:

• High-temperature applications up to 425°C where elastomer seats would degrade

• High-pressure systems requiring robust sealing performance

• Corrosive or abrasive media including steam, oil, gas, and chemical fluids

• Extreme cold environments as low as -45°C, commonly encountered in Siberian oil fields

• Industrial sectors such as oil & gas, petrochemical, power generation, chemical processing, metallurgy, and water treatment

With a design life significantly longer than resilient seated alternatives, GOST metal seated gate valves offer lower whole-life cost and reduced maintenance frequency, making them a cost-effective investment for long-term industrial operations.
