China GOST Standard Gate Valve 30ch6br - DN50-DN1200, PN10/PN16, Factory Suppliers for Chemicals, Water, Steam, Oil
🔍 Description
✅
The GOST Gate Valve 30ch6br is engineered for reliable shutoff in high-pressure pipelines, especially in engineering projects and water distribution systems.
This valve features a parallel double-disc design, which offers superior sealing performance and lower friction during operation—making it suitable for both horizontal and vertical installations.
Its wedge-free structure allows for easy opening and closing without jamming, even under fluctuating pressure. The valve body is typically made from ductile iron or cast steel, while the sealing surfaces can be fitted with stainless steel or bronze overlays for improved wear resistance. It is ideal for use in power plants, municipal networks, industrial processing, and oil & gas applications.
This GOST Gate Valve 30ch6br complies with multiple international standards, including EN and ANSI, and is available in a wide range of sizes and pressure ratings. Its robust construction and easy maintenance design make it a dependable choice for systems requiring precise flow isolation and long service life.
As one of China's top valve manufacturers, we offer high-quality gate valves built for demanding applications, backed by advanced manufacturing and strict quality control.
