About Flow-Adjustment Valves
More
Threaded Flow-Adjustment Valves
These valves gradually open and close to adjust and regulate flow.
Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than lever handles.
Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.
316 stainless steel valves are more corrosion resistant than bronze valves.
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.

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.
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.

Socket-Connect Flow-Adjustment Valves
- Valve Type: Globe
- For Use With: Water, Oil, Argon, Helium, Krypton, Neon, Xenon
- Specifications Met: ASTM A351
Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. These valves gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. They 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. Body is 316 stainless steel for excellent corrosion resistance.
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.
