F400 / F1400
Full Port Ductile Iron
Single Chamber Basic Valve with
Mechanical Check Feature
The Watts ACV Models F400 and F1400 are single chamber
basic valves that incorporate a two-piece telescoping 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. The lower portion of this
two-piece assembly is a mechanical check feature, which acts
independent of diaphragm position or pilot control system, and
provides immediate check action when flow ceases.

Maximum continuous flow based on velocity of 20 ft. per second.
Maximum intermittent flow based on velocity of 25 ft. per second.
The Cv 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.
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)
