The Watts ACV Models M100 and M1100 are full port, single
chamber basic valves that incorporate a one-piece disc and diaphragm assembly. This assembly is the only moving part within
the valve allowing it to open, close, or modulate as commanded
by the pilot control system.

Cv factor can be used in the following equations to determine Flow (Q) and Pressure Drop (∆P):
Cv factor can be used in the following equations to determine Flow (Q) and Pressure Drop (∆P):
Q (Flow) = Cv√∆P ∆P (Pressure Drop) = (Q/Cv)
Q (Flow) = Cv√∆P ∆P (Pressure Drop) = (Q/Cv)
