Shanghai Pudong Hanwei Valve Co., Ltd. was established in 1992 and is located in Pudong New Area, Shanghai. Adjacent to Shanghai Pudong International Airport and Metro Line 2, the company enjoys convenient transportation. It was certified as a Shanghai High‑tech Enterprise in 2007. In the early stage of operation, the company focused on the localization replacement of imported valves for large state‑owned petrochemical facilities.

The company’s leading products include ball valves, butterfly valves, gate valves, globe valves, check valves, 24‑way rotary valves and other special valves. Its business covers oil‑gas industry, PTA chemical industry (titanium valves) and macromolecule industry (24‑way rotary valves).

The company holds multiple patented products with independent intellectual property rights. Among them, the simulated moving‑bed adsorption‑separation equipment — the 24‑way rotary valve, was awarded the Second Prize for Scientific and Technological Progress. It serves as critical equipment for large aromatic‑hydrocarbon and ethylene combined units, and can be applied in chemical separation as well as chromatographic separation for bio‑engineering scenarios.

As a specialized valve manufacturer, Hanwei Valve follows its independent technical development path. With focus on oil‑gas sector while covering PTA and macromolecule‑related applications, the company keeps optimizing and upgrading its product technologies. It has accumulated mature practical experience in material processing and welding for duplex steel, INCONEL, MONEL, cupronickel alloys and titanium materials.
