Description
The Watts ACV Models M518 and M1518 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.
