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 com-
manded 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.

Mechanical Check Feature.

Mechanical Check Feature.
