The A350 Gr.LF2 150LBS Globe Valve is a low-temperature service valve designed for reliable shut-off and throttling in cryogenic and cold-environment applications. The body is forged from A350 Gr.LF2—a carbon steel grade specifically heat-treated for impact resistance at sub-zero temperatures down to -46°C (-50°F). Rated for 150LBS (Class 150), it is suitable for moderate-pressure systems in petrochemical plants, LNG terminals, refrigeration systems, and offshore platforms. The globe valve design offers precise flow control with a linear flow characteristic. Its forged construction ensures structural integrity, while optional bonnet extensions can accommodate cold-box insulation requirements. This valve combines durability, safety, and performance in demanding low-temperature environments.
