Product Introduction – GOST Gate Valve (-29°C to 425°C) for the Russian Market
Our GOST Carbon Steel Flanged Gate Valve, engineered to operate at temperatures as low as -29°C, is the ideal solution for cold-climate applications across Russia. Designed in accordance with GOST standards, this valve offers dependable shut-off and long-term durability in low-temperature and high-pressure environments.
Constructed from high-grade carbon steel (WCB), the valve body maintains excellent mechanical strength and toughness even under sub-zero temperatures. Special low-temperature treatments and precise machining ensure that the valve remains resistant to brittleness, leakage, and performance degradation—common issues in freezing conditions.
This valve is especially suitable for northern regions of Russia, where extreme cold is a constant challenge for industrial operations. From oil fields in Siberia to gas pipelines in remote territories, equipment reliability at low temperatures is critical to safety and efficiency. Our gate valve guarantees tight sealing performance, minimal thermal expansion risk, and safe operation even during harsh winter conditions.
