Field-Proven Through Major Engineering Projects
Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s Longwan District, has established its reputation through the reliable performance of its forged steel and cryogenic valves in demanding engineering projects across petrochemical, power, and natural gas sectors. The company’s products have been deployed in coastal nuclear power facilities and western oil fields, where its forged steel check valves have recorded extended periods of leak-free operation under extreme conditions. In LNG terminals and air separation units operating as low as -196°C, the company’s cryogenic valve series, utilizing austenitic stainless steel and deep cold processing, has effectively addressed material embrittlement and sealing challenges.
Quality verification is embedded throughout the manufacturing process, with each valve undergoing 36 strict inspection procedures and pressure resistance up to 27.5MPa. The company’s commitment to practical engineering validation is further supported by its Phase III AI Super Smart Factory, designed to enhance production capacity and quality consistency. Through continuous refinement of forged steel and cryogenic valve technologies, Zhengyuan Valve Group maintains its focus on delivering reliable solutions for critical industrial infrastructure.
