Chrome molybdenum steel gate valve
Manufactured from premium chrome molybdenum alloy steel materials such as WC6, WC9, F11, F22, and F91, this gate valve delivers outstanding resistance to high temperatures, pressure, oxidation, and creep deformation. It ensures reliable shut-off performance and extended service life in power generation, refinery, and petrochemical systems.
Chrome molybdenum steel gate valve
The Chrome Molybdenum Steel Gate Valve is designed for severe service conditions involving elevated temperatures and pressures. Utilizing chromium-molybdenum alloy steel construction, the valve provides superior mechanical strength, oxidation resistance, and thermal stability compared to conventional carbon steel valves.
The valve features precision-machined wedge gates and hard-faced sealing surfaces to ensure tight shut-off performance and low leakage rates. It is widely used in steam pipelines, thermal power plants, petrochemical facilities, oil refineries, and industrial process systems where long-term reliability is critical.
Our Chrome Molybdenum Steel Gate Valves are manufactured under strict quality systems and can be supplied with complete international certifications:
