Description
The WATTS ACV Models F518 and F1518 are full port, dual 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 or close 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.
When pressure is applied to the upper diaphragm chamber and released from the lower diaphragm chamber, the valve travels
to a closed position. When pressure is applied to the lower diaphragm chamber and released from the upper diaphragm
chamber the valve travels to a full open position.
Model F518: Globe Pattern Dual Chamber Basic Valve with Mechanical Check Feature.
Model F1518: Angle Pattern Dual Chamber Basic Valve with Mechanical Check Feature.
