Technical Data
Our cryo ball valve PM is a 1-piece, laser-welded cryogenic design in 1.4404. The cryogenic ball valves are specially designed for cryogenic media, such as liquid gases CO₂, N₂, Ar, O₂ natural gas (LNG), in cryogenic process plants. With a spring-loaded seat ring system, the valve guarantees easy switching of the ball down to a temperature of -196°C. In addition, the ball valve has an integrated pressure relief system, a blow-out-proof switching shaft, virtually no dead space, and a pre-stressed stop-bushing seal in accordance with TA-Luft, which ensures the highest possible process reliability.
