8. Welded Bonnet Advantages

9. Features & Applications

• Key Features:
• Welded Bonnet Construction: Threaded-in and strength-welded bonnet eliminates gasket and provides zero leakage at body-bonnet joint .
• High Pressure Capability (2500LB): Designed for extreme high-pressure applications up to 420 bar (6000 PSI) .
• Forged Body Construction: Close die forged steel provides superior strength, uniform grain flow, and absence of porosity .
• Integral Seat: Machined directly into body for maximum strength and reliability .
• API 602 Design: Meets stringent industry standards for forged steel valves .
• Excellent Throttling Control: Globe valve design provides precise flow regulation .
• Backseat Design: Protects stem packing when valve is fully open .
• OS&Y Design: Rising stem provides visual indication of valve position .
• High Temperature Capability: Suitable for temperatures up to 550°C with appropriate materials .
• Compact & Lightweight: Welded bonnet design reduces weight compared to bolted bonnet .
• Multiple End Options: Available in socket weld, butt weld, or threaded connections .
• Fugitive Emission Control: Welded bonnet eliminates potential leak path, ideal for critical service .
• Main Applications:
• High-Pressure Steam Systems: Power plants, boiler systems .
• Refineries & Petrochemical: Hydrocarbon processing, high-pressure fluid control .
• Oil & Gas Production: Wellhead control, high-pressure gathering systems .
• Chemical Processing: Corrosive fluid handling (with SS materials) .
• High-Temperature Applications: Up to 550°C with alloy materials .
• Critical Service: Where zero leakage and maximum reliability are required .
• Instrument Connections: Small bore high-pressure isolation .
