Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s Longwan District, has developed a diverse valve portfolio serving multiple industrial sectors. Its forged steel gate, globe, check, and ball valves are widely applied in petrochemical, power generation, metallurgy, natural gas, and water treatment industries. The company offers a wide range of pressure ratings and temperature capabilities, with body materials including carbon steel, alloy steel, stainless steel, Monel, and lined configurations to suit varied service conditions. In petrochemical applications, anti-sulfur gate valves resist hydrogen sulfide stress corrosion. In power generation, forged steel check valves feature a patented low-torque spring-assisted closing system to eliminate water hammer. For LNG and cryogenic services, valves undergo deep cold treatment to prevent low-temperature embrittlement. With comprehensive quality control from raw material verification to finished product testing, Zhengyuan Valve Group maintains its focus on delivering reliable valve solutions across diverse industrial applications.
