Cryo Ball Valve PM Type PMT

**Sales only in Germany**

PM series (PMT type)

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 -200°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.
