LF2M Cryogenic Forged Trunnion Ball Valve

NSV LF2M Cryogenic Forged Trunnion Ball Valve

Manufactured from ASTM A350 LF2M low-temperature carbon steel forgings. Engineered for demanding cryogenic service. The forging process eliminates casting defects. Ensures superior density and impact resistance. Guarantees reliable operation down to -60℃ without risk of brittle fracture. A full-bore design combined with standard butt-weld ends provides minimal pressure drop. Delivers a leak-free connection equivalent to the pipeline itself. Ideal for LNG, ethylene, and deep-cold fluid systems.

Key Features

LF2M Forged Body: Normalized and tempered. Charpy V-Notch impact tested at -60°C to guarantee low-temperature toughness.

Trunnion Mounted Design: Dual stem support balances media pressure. Reduces operating torque. Extends seal life.

Double Piston Effect Seats: Standard DPE seats provide bi-directional sealing. Cavity auto-relief prevents overpressure damage.

Butt-Weld Ends: Bevels machined per ASME B16.25. Offers weld integrity equal to pipe. Eliminates flange leakage risks.

Safety Features: Anti-static device. Anti-blowout stem. Fire-safe design compliant with API 607 and 6FA standards.
