Description
The WATTS ACV Models M500 and M1500 are full port, dual 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 or close as
commanded by the pilot control system.
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. When pressure is balanced between the upper and lower
diaphragm chambers, the valve will hold an intermediate position until commanded to modulate open or closed by the
pilot control system
.
