LF2M Trunnion Ball Valve

NSV LF2M Trunnion Ball Valve

Engineered for extreme cryogenic and high-pressure applications, this valve features an ASTM A350 LF2M forged steel body that maintains exceptional impact toughness and mechanical strength at temperatures as low as -60℃. The trunnion mounted design effectively eliminates medium pressure thrust on the seat, ensuring stable operating torque and reliable sealing even under PN160 high pressure. It is the ideal choice for safe shut-off in LNG terminals, ethylene plants, and long-distance pipelines in cold regions.
