Class 1500 API 600 High Temperature High Pressure Flanged Angle Globe Valve

Engineered for the most extreme thermal and pressure conditions, the Class 1500 API 600 High Temperature High Pressure Flanged Angle Globe Valve delivers uncompromising safety and precise flow regulation.

Designed strictly to API 600 standards, this valve is built to withstand severe thermal cycling and ultra-high internal pressures up to Class 1500. It features a robust angle body configuration that minimizes pressure drop and resists erosion in high-velocity steam flows, combined with a heavy-duty flanged connection (ASME B16.5) for secure installation. Equipped with a pressure seal or heavy-duty bolted bonnet, this HTHP angle globe valve ensures reliable throttling, zero-leakage shut-off, and seamless integration into critical main steam, reheat steam, and high-pressure feedwater systems in thermal and nuclear power plants.

Key Features & Benefits

· API 600 Standard Compliance: Designed and manufactured strictly to API 600 specifications, ensuring dimensional compatibility, structural safety, and reliable performance in global petroleum and petrochemical infrastructure.

· Angle Body Design for HTHP Service: The 90-degree angle configuration reduces flow resistance and minimizes erosion in high-velocity steam services, while also saving valuable installation space in compact piping layouts.

· Class 1500 Structural Integrity: Engineered with heavy-duty wall thickness and high-strength alloy materials to withstand extreme thermal cycling and severe pressure surges without deformation or failure.

· Precise Throttling & Shut-off: The plug-shaped disc moves linearly along the valve seat, with the port change directly proportional to the disc stroke, making it ideal for both precise flow regulation and reliable isolation in ultra-high-pressure systems.

· Robust Flanged Connections: Compliant with ASME B16.5 standards, ensuring easy installation, secure sealing (RF or RTJ), and leak-proof performance in Class 1500 piping systems.

· Stellite Hard-Faced Trim: Seat rings and disc seating surfaces are overlaid with Stellite 6 (Co-Cr-W alloy) to resist severe erosion, high-temperature corrosion, and galling in aggressive steam and oil flows.

FAQ

Q: Why choose an angle globe valve for Class 1500 HTHP applications?
A: Angle globe valves have a 90-degree body configuration that reduces flow resistance and minimizes erosion in high-velocity steam services. For Class 1500 HTHP applications, the angle design also helps manage thermal stress and saves installation space in compact piping layouts.

Q: What is the difference between API 600 and API 623 for globe valves?
A: API 600 is the standard for steel gate valves, but it is also commonly referenced for high-performance globe valves in the oil and gas industry. API 623 is the specific standard for steel globe and globe stop and check valves. Both ensure rigorous design and testing, but API 600 is often preferred for severe service applications requiring extra structural integrity.

Q: What materials are suitable for Class 1500 HTHP angle globe valves?
A: Common materials include WCB for temperatures up to 425°C, WC6/WC9 for temperatures up to 595°C, and F304H/F316H stainless steel for temperatures up to 695°C. The material selection depends on the specific operating temperature and pressure conditions of the application.
