Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s “China Valve City,” applies advanced die forging—rather than cold drawing—as the primary forming process for its forged steel gate, globe, check, and ball valves. Die forging compresses heated steel billets under high pressure to produce valve bodies with dense, defect‑free metallurgical structures, eliminating porosity and inclusions and enhancing strength and pressure‑bearing capacity.

  The company’s forged steel valves feature pressure ratings from 150Lb to 2500Lb and temperature ranges from -196°C to 800°C. Sealing faces are overlaid with Stellite hard alloy and precision‑lapped to ensure reliable sealing under high‑temperature, high‑pressure, and corrosive media. With pressure ratings from 150Lb to 2500Lb and temperatures from -196°C to 800°C, these valves serve petrochemical, power, and other critical industries through systematic quality assurance and API 6D, GB/T compliance.
