    Threaded Flow-Adjustment Valves for Cryogenic Liquid

    Designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, and liquid nitrogen, these valves are cleaned and bagged to meet CGA G-4.1 standards for oxygen service. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.

    Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

    Compact Threaded Flow-Adjustment Valves for Cryogenic Liquid

    Often used with portable cryogenic cylinders, these valves are a third of the height of other valves for cryogenic liquid. They are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, and liquid nitrogen; all are cleaned and bagged to meet CGA G-4.1 standards for oxygen service. These valves gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. They have a nonrising stem that stays in the same position whether the valve is open or closed.
