Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s Longwan District, brings a practical, engineering-driven perspective to environmental equipment applications. With over a decade of manufacturing experience, the company produces gate, globe, check, and ball valves that are integral to pollution control systems including flue gas desulfurization, industrial wastewater treatment, and exhaust gas management . These applications demand superior corrosion resistance and sealing reliability—qualities Zhengyuan addresses through a comprehensive material selection strategy. The company offers valves in carbon steel, stainless steel, alloy steel, Monel, and lined configurations, with pressure ratings from 150Lb to 2500Lb and temperature ranges from -196°C to 800°C to accommodate diverse environmental process conditions .

For aggressive environments like wet FGD systems where lime/gypsum slurries cause rapid corrosion, Zhengyuan supplies duplex stainless steel and Monel alloy valves. In less severe service, 316L stainless steel valves provide robust chloride resistance for cooling water and wastewater systems . The company maintains comprehensive quality control from raw material verification through finished product testing, supporting its quality-first manufacturing philosophy. Through continuous refinement of forged steel valve technologies and material selection aligned with environmental service requirements, Zhengyuan Valve Group maintains its focus on delivering reliable valve solutions for critical environmental protection infrastructure .
