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 value is the flow rate in US GPM at 60°F that will cause a 1psi 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 (∆P):
Q (Flow) = C
v
√∆P ∆P (Pressure Drop) = (Q/C
v
)
