F100 / F1100 — Full Port Ductile Iron Single Chamber Basic Valve
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
