Forged steel globe valve is a commonly used cut-off valve, which is mainly used to connect or cut off the medium in the pipeline. The valve designed to API602 and tested to API598 has an outside screw and yolk with rising stem. Forged steel globe valve is suitable for class 150（PN100）~2500（PN420）, working temperature -29°C~425°C (carbon steel) or -29°C~500°C (stainless steel) pipeline. Different materials can be applied to various media such as water, steam, boiler, Oil & Gas, and acetic acid respectively. Forged steel globe valve has small fluid resistance, wide applicable pressure & temperature range, unlimited media flow direction, and good sealing performance.
Applications for Forged Globe Valve
Forged globe valves are robust, high-performance valves designed for demanding industrial environments. Their forged construction ensures superior strength and durability, making them suitable for critical applications.
1. High-Pressure and High-Temperature Systems
Oil & Gas Pipelines: Forged globe valves (e.g., Class 1500–2500) are used in upstream and midstream operations for throttling and isolating high-pressure fluids like oil, gas, and steam.
Power Plants: Carbon steel (A105N) and alloy steel variants handle steam and boiler feedwater systems at temperatures up to 425°C.
Hydrocarbon Processing: API 602-compliant valves ensure leak-tight performance in refineries for crude oil and gas refining.
2. Corrosive and Hazardous Fluids
Chemical Plants: Stainless steel (CF8M/316 SS) and nickel alloy (Hastelloy, Monel) valves resist acids, chlorides, and aggressive chemicals.
Bellow Seal Variants: Forged bellow seal globe valves prevent fugitive emissions in toxic or volatile fluid systems (e.g., ammonia, chlorine).
3. Steam Distribution and HVAC
Steam Lines: Forged steel valves with bolted bonnets and spiral-wound gaskets ensure reliable sealing in high-temperature steam applications.
Heating Systems: Used in district heating and industrial HVAC for precise flow control.
4. Marine and Offshore Applications
Seawater Systems: Bronze or duplex stainless steel valves resist saltwater corrosion in shipboard cooling and ballast systems.
Offshore Platforms: API 602 valves meet stringent safety standards for oil and gas extraction in harsh marine environments.
5. Critical Infrastructure and Utilities
Water Treatment: Cast iron or bronze valves regulate flow in municipal water supply and wastewater treatment plants.
Nuclear Facilities: Alloy steel valves with pressure ratings up to Class 2500 ensure safety in coolant and auxiliary systems.
