ASTM A350 LF2 ball valve utilizes forged carbon/low-alloy steel designed specifically for low-temperature services. It offers exceptional notch toughness and is ideal for demanding industries like oil, gas, and petrochemical refining where sub-freezing operating temperatures are expected
Specifications & Features
- Body Material: Forged ASTM A350 LF2 (commonly Grade Class 1 for temperatures down to \(-46^{\circ}\text{C}\)).
- Trim Material: Often paired with SS316, F6A, or other corrosion-resistant alloys.
- Temperature Range: Generally \(-46^{\circ}\text{C}\) to \(+200^{\circ}\text{C}\).
- Valve Types: Trunnion mounted, floating, or Double Block and Bleed (DBB).
- Standards: API 6D, API 608, and ISO 17292 compliance.
- End Connections: Flanged (RF/RTJ), Threaded (NPT), or Butt-Weld
Applications
LF2 ball valve is the industry standard for:
- Liquefied Natural Gas (LNG) processing and transport.
- Onshore and Offshore Pipelines in cold climates (e.g., Arctic regions).
- Refrigeration systems and low-temperature process fluids
