Full Port Ductile Iron
Dual Chamber Basic Valve
The Watts ACV Models F500 and F1500 are full port, dual cham-
ber 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.
