About Flow-Adjustment Valves

Snap-Shut Threaded Flow-Adjustment Valves
Also known as whistle valves, these open and throttle as force is applied to the lever and automatically close upon release. They’re commonly used for spraying, washing, and other applications that require manual discharge of liquid and air. All have a nonrising stem that stays in the same position whether the valve is open or closed.
Pull-activated lever handles open the valve when you pull the handle upward. Attach a cord or chain to the hole in the handle for remote operation.
Push-activated lever handles open the valve as downward pressure is applied.

Compact Threaded Flow-Adjustment
Valves for Cryogenic Liquid
- Valve Type: Globe
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen
- Specifications Met: CGA G-4.1
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.
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.
