Apart from operating at very low temperatures, these valves operate where the fluid can be a gas or a liquid and therefore must be designed and tested to accept the pressure and temperature gradients as the fluid changes state.
At the higher temperatures we have the L20 high pressure solenoid valve that was specifically designed for liquid CO2 used in fire suppression, laboratory and special effects applications, with or without ATEX certification.
At -196C we have the L88/L89 2 way solenoid valves that have been designed and proven not to freeze up under operation which is a common problem for other manufacturers.
We also have the Boscarol range of globe, check, manifold, regulating and economizer valves which have been proved over 50 years of continuous manufacturing. These products can be customised to suit each requirement with a large variety of options.

Common cryogenic fluid temperatures
Liquid CO2 -78.5C
Liquid nitrous oxide NO2 -88C
Liquid methane CH4-161.5C
Liquid oxygen -183C
Liquid argon -186C
Liquid Nitrogen -196C
Liquid Hydrogen -260C
Liquid Helium -269C
Our range of cryogenic valves are suitable for temperatures down to -196C. For other gases and temperatures below this, very specialist solutions are required and often referred to as 2K or 4K valves.
