Nuclear‑grade valves are critical components ensuring safe operation of nuclear power plants, used to control the flow and pressure of media such as coolant and steam. They shall feature high tightness, radiation resistance and corrosion resistance to withstand extreme service conditions. Common types include gate valves, globe valves and check valves, which are widely deployed in reactor cooling systems, steam generators and auxiliary pipelines to guarantee stability and reliability of nuclear power systems. The company attaches great importance to quality and safety for nuclear facilities. A complete nuclear quality assurance system has been established in accordance with HAF003 covering all key links. Application for the license for design and manufacture of nuclear‑grade valves has been submitted. The prototype parameters can satisfy most requirements for nuclear‑grade control valves of existing nuclear power units. Over the past more than ten years, the company has supplied over 3000 non‑nuclear‑grade valves for multiple nuclear‑power‑related entities with satisfactory operating references.
