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.
