Threaded Flow-Adjustment Valves

Straight with Lever Handle

Straight with Flow-Indicating Lever Handle

These valves gradually open and close to adjust and regulate flow.

Lever handles open and close faster than wheel handles.

Flow-indicating lever handles show the proportion the valve is open.

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.
