Maximum continuous flow based on velocity of 20 ft. per second.
Maximum intermittent flow based on velocity of 25 ft. per second.
The C
V
factor of a valve 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.
C
V
factor can be used in the following equations to determine Flow (Q) and Pressure Drop (
r P):
Q (Flow) = C
V
r P
rP (Pressure Drop) = (Q/C
V
)
