IMI PBM

Marine Cryogenic Valve

Cryogenic ball valve engineered for reliable sealing and flow control at extreme low temperatures.

Maintains secure sealing and flow alignment throughout extreme cryogenic temperature cycles.
Reduces risk of leakage from thermal expansion with independently bolted valve ends.
Supports long-term service life with actuation-ready stem and live-loaded packings.

The IMI PBM Cryogenic Marine Valve is designed to deliver reliable shut-off and sealing in ultra-low temperature environments down to -252°C. Ideal for cryogenic service aboard submarines, it features a keyed stem-ball interface for proper orientation and flow alignment. Energised seat back gaskets and live-loaded stem packings maintain tight sealing performance throughout thermal cycling. Each valve end is independently bolted to manage thermal expansion stresses, ensuring leak-free operation over time. Available in a wide range of corrosion-resistant alloys and ANSI pressure classes up to 413 bar, this compact, actuation-ready valve is built for safety-critical cryogenic applications.
