Low Emission Cryogenic Valves

Cryogenic valves, or low temperature valves, are built to work safely and reliably in very cold environments. They follow international standards like ISO, API, BS, and are tested to make sure they meet both normal and extremely low temperature requirements. These valves are commonly used in industries like LNG (liquefied natural gas), air separation, ethylene, and liquefied petroleum gas.

To prevent leaks and ensure long-term safety, the valves use API 622-certified low-leakage stem packing. This keeps the seal around the stem tight, even during pressure changes or temperature swings. These valves come in several types, including ball, butterfly, gate, globe, and check valves, and they are available in a variety of sizes and pressure ratings.
