Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s “China Valve City,” supports the localization of nuclear power valves. The company uses advanced die forging to produce valve bodies with dense metal structures and high strength. Its forged steel gate, globe, check, and ball valves feature pressure ratings from 150Lb to 2500Lb and temperature ranges from -196°C to 800°C, with materials including carbon steel, alloy steel, stainless steel, and duplex stainless steel.

  Sealing faces are overlaid with Stellite hard alloy and mirror-finished to minimize leakage risks. Each valve undergoes shell strength testing at 1.5 times the rated pressure and seat leakage testing. With ISO9001 certification and API 6D, GB/T compliance, the company provides reliable fluid control solutions for domestic nuclear power projects.
