    Long-Life Pressure-Regulating Valves for Cryogenic Liquids

    Image of Product. Front orientation. Pressure-Regulating Valves. Long-Life Pressure-Regulating Valves for Cryogenic Liquids.
    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.

    Vacuum Breakers for Chemicals

    A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum-breaking valves, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.

    Fast-Acting Pressure-Relief Valves for Cryogenic Liquids

    Cleaned and bagged for oxygen service and other high-purity applications, these valves can withstand the extreme cold of liquid argon, liquid nitrogen, and liquid oxygen. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. All have a vented relief port to exhaust discharge directly.

    Pressure-Relief Valves for Cryogenic Applications

    Image of Product. Front orientation. Pressure-Relief Valves. Pressure-Relief Valves for Cryogenic Applications.
    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.
    Riser Tubes—Riser tubes (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.
    Adapters—Adapters (sold separately) convert the valve relief-port connection from UNEF female threads to NPT female threads.
