Gas media Handwheel Rising Stem Resilient Seated Hard Seal Carbon Steel GOST Gate Valves and Fitting OEM

Our GOST-compliant gate valves are engineered for reliable gas media handling, featuring a rising stem design with a durable handwheel for precise manual operation. Constructed from carbon steel (WCB/ASTM A216), these valves ensure corrosion resistance and structural integrity under high-pressure gas applications. The resilient seated hard seal combines a metal seat with advanced elastomer materials, providing zero-leakage performance and extended service life in harsh environments.

Crafted from WCB carbon steel, the valve body resists corrosion and thermal stress, suitable for temperatures ranging from -20°C to 235°C. The handwheel operation provides manual control with ergonomic efficiency, ideal for environments requiring fail-safe mechanical actuation. Compliant with GOST standards , the valves meet rigorous specifications for gas distribution systems in oil, gas, and petrochemical industries.
