Engineered for the Rigors of the CIS Market
In the vast industrial landscapes of Russia and the CIS countries, fluid control components must withstand more than just internal pressure—they must survive some of the harshest environmental conditions on Earth. Veyron Valve’s GOST Gate Valve series is designed in strict compliance with GOST 5762 (design) and GOST 33259 (flange connections). Unlike standard utility valves, our GOST series is built with the heavy-wall thickness and specific metallurgy required to maintain structural integrity in district heating, oil extraction, and power generation sectors across Eastern Europe and Northern Asia.
Metallurgical Excellence: The 09G2S Advantage
One of the most critical differentiators of the Veyron GOST series is our adherence to Russian material standards.
- Climatic Execution (UHL/KhL): For projects in Arctic or sub-zero regions, we offer valves cast from 09G2S (Low Alloy Steel). This material is specifically chosen for its high impact toughness at temperatures as low as -60°C, preventing the "brittle fracture" that common carbon steels (like WCB) might experience in the Siberian winter.
- Standard Carbon Steel (Steel 20/25L): For temperate climates, we utilize high-quality Steel 20 or 25L, providing a cost-effective yet robust solution for steam and water applications where reliability is the primary KPI.
Precision Sealing & Flange Geometry
The sealing performance of a GOST valve is defined by its "Trim" and its connection type.
- Wedge Dynamics: Our valves feature a Wedge (Klin) design, available in both solid and elastic configurations. The seating surfaces are typically hardfaced with stainless steel (corrosion-resistant) or brass, depending on the fluid medium, ensuring a "Class A" leakage rate according to GOST 9544.
- Flange Executions: Understanding that GOST 33259 specifies different "Executions" (from Execution 1 to Execution 9), Veyron Valve provides precision-machined flange faces to match your specific gasket requirements. Whether your project calls for a standard Raised Face or a complex Tongue-and-Groove interface, our CNC machining ensures a perfect, leak-proof fit.

Field Reliability and Maintenance
Veyron Valve acknowledges the logistical challenges of remote industrial sites. Our GOST gate valves feature a Full-Bore design to minimize flow resistance and facilitate "pigging" operations in pipelines. The Stuffing Box is designed for easy access, utilizing high-density graphite packing that can be adjusted or replaced to maintain a stem seal under high-pressure conditions. Every valve is finished with a weather-resistant protective coating designed to resist the corrosive effects of industrial atmospheres and salt-laden environments.
Documentation & Compliance
We understand that the CIS market requires rigorous documentation. Every Veyron GOST gate valve is accompanied by a technical passport and a material certificate in accordance with EN 10204 3.1, ensuring full traceability from the foundry to the final installation site.
