SJ661YPower station globe valve
The Power Station Globe Valve is specially designed for steam, feedwater, condensate, and thermal oil systems in power plants. Manufactured from high-strength alloy steel with precision-machined sealing surfaces, it delivers excellent shut-off performance, superior pressure resistance, and dependable operation under extreme temperature and pressure conditions.
Power station globe valve
The Power Station Globe Valve is a critical isolation and regulation valve widely used in thermal power stations, nuclear power facilities, industrial boilers, and energy infrastructure projects. Designed to withstand severe service conditions, it provides accurate flow control and reliable shut-off for high-energy fluids.
Constructed from forged or cast alloy steel, the valve features excellent resistance to thermal shock, erosion, and corrosion. Available in manual, bevel gear, electric, pneumatic, and electro-hydraulic configurations, it supports both conventional and automated power plant systems.
Our Power Station Globe Valves are manufactured and tested according to international standards:
