GOST Butterfly Valve

A GOST butterfly valve is a lightweight, quarter-turn rotary isolation and throttling valve designed, built, and pressure-tested in compliance with the national standards of the Russian Federation and CIS region (GOST 12521 and GOST 9544). Featuring a slim, compact disc and a resilient-seated or metal-to-metal offset seat configuration, this valve offers exceptional space savings and rapid quarter-turn operation. The valve body flange connections, face-to-face lengths, and pressure-temperature ratings conform strictly to GOST standards (such as GOST 33259 for flanges and GOST 54808 for leakage testing), ensuring seamless integration into regional systems. Piping contractors, utility engineers, and energy infrastructure developers in GOST-regulated territories can secure perfect physical compatibility and certified sealing performance by importing GOST butterfly valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
