GOST Standard Gate Valve

A GOST standard gate valve is a heavy-duty, multi-turn linear-motion shut-off valve designed, manufactured, and quality-tested in strict compliance with Russian national standards, including GOST 5762 and GOST 9544. Utilizing a heavy wedge (either solid, flexible, or double-disc) driven perpendicular to the flow path, it provides an unobstructed, full-bore passage with virtually zero pressure drop and minimal flow turbulence when wide open. The valve's flange dimensions, nominal pressures, and nominal diameters are designated according to the GOST metric system, ensuring simple, drop-in replacement in legacy pipelines. Gas pipeline developers, water system managers, and petroleum engineers working with regional standards can guarantee pressure boundary safety and standard-compliant dimensions by importing certified GOST standard gate valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
