Cleaned and bagged to meet CGA G-4.1 for oxygen service and other high purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Set pressure is not adjustable.

Valves are not intended for direct contact with cryogenic liquids. Risers (sold separately) are required to convert cryogenic liquids into gases before they contact the valve. 3/8 NPT valve requires a 1/2 NPT × 3/8 NPT bushing when using a riser.
