Pressure-Regulating Valves for Cryogenic Liquids
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
- Temperature Range: -320° to 150° F
These valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

Tank-Mount Pressure-Regulating
Valves for Cryogenic Liquids
- For Use With: See Table
- Temperature Range: -20° to 120° F
Automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. These valves have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves come with a gauge to monitor outlet pressure. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.
Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Extended-Life Pressure-Regulating
Valves for Cryogenic Liquids
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
- Temperature Range: -320° to 150° F
For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They have an internal strainer to trap debris.
