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.
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.

Low-Pressure Threaded Flow-Adjustment Valves
- Valve Type: Globe
- For Use With: Water
- Specifications Met: See table
Use these valves for boiler maintenance and other low-pressure plumbing applications. 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.
