Zhengyuan Valve Group Co., Ltd. supplies stainless steel and duplex stainless steel gate, globe, check, and ball valves for industrial water systems. Its stainless steel valves resist chloride corrosion in circulating cooling water, while duplex stainless steel valves offer higher strength and better resistance to chloride stress corrosion for seawater cooling. For high-temperature steam systems, forged steel valves maintain oxidation resistance.

  Sealing faces are overlaid with hard alloy and precision-lapped for reliable closure. With pressure ratings from 150Lb to 2500Lb and temperature ranges from -196°C to 800°C, Zhengyuan provides reliable fluid control for water systems in petrochemical and power applications.
