The C
v
Factor of a value is the flow rate in US GPM at 60° F that will cause a 1 psi drop in pressure.
The factors stated are based upon a fully open valve.
Cv factor can be used in the following equations to determine Flow (Q) and Pressure Drop (∆ P):
Q (Flow) = C
v
∆ P ∆ P (Pressure Drop) = (Q/C

NOTE: The above chart is a suggested guide. Inlet pressure, outlet pressure, minumum, normal and maximum flow rates should
be considered for specific valve sizing. Contact Watts ACV for details.
