Product Description
Master the Flow in Critical Applications
In high-stakes pipeline systems, you need more than just a valve—you need a guarantee of absolute isolation and reliability. Our Large Diameter GOST Gate Valves are engineered for the most demanding industrial environments, providing superior shut-off performance, unmatched durability, and long service life. They are the trusted choice for oil & gas, petrochemical, power generation, and major infrastructure projects.
Engineered for Performance & Endurance
Full GOST Standard Compliance
Designed, manufactured, and tested in strict accordance with key Russian GOST standards (GOST 3706, GOST 5762, and related specifications). This ensures seamless compatibility and approval for projects in CIS regions and globally where GOST standards are specified.
Robust Pressure Integrity & Construction
Fabricated from high-strength materials including cast iron, carbon steel, stainless steel, and alloys to suit your service conditions. Features reinforced body and sturdy wedge (solid or flexible) or parallel disc design for minimal pressure drop when open and bubble-tight seal when closed.
Large Bore for Maximum Flow Efficiency
Specifically built for large-scale pipelines from DN200 (8") up to DN1200 (48") and beyond. The optimized full-bore design provides excellent flow coefficient (Cv), minimizing turbulence and pressure loss to enhance overall piping network efficiency.
Reliable Sealing for Longevity
Seat and wedge/disc sealing surfaces are often hard-faced with wear-resistant alloys (e.g., Stellite) for exceptional resistance to abrasion, corrosion, and galling. Precisely engineered stuffing box with high-quality graphite or PTFE packing ensures reliable, long-term stem sealing and extended maintenance intervals.
Flexible Actuation Options
Available with manual operation (handwheel or gearbox), as well as electric, pneumatic, or hydraulic actuators. Enables easy integration into any control scheme, from local manual use to fully automated remote systems.
Rigorous Quality Assurance
Every valve undergoes stringent testing including shell tests, seat leakage tests, material verification, and operational checks. We guarantee 100% compliance with specifications, delivering a product you can trust from day one.
Typical Applications
Oil & Gas transmission lines and station isolation
Petrochemical and chemical processing plants
Power Plants (thermal & nuclear) - water supply and steam lines
Large-scale water supply, distribution, and wastewater treatment networks
Shipbuilding and offshore platform piping systems
