Full Port Ductile Iron Dual Chamber Basic Valve
ACV Schematic - Series LF985GD
This Ames ACV is a full port, dual chamber basic valve that
incorporates 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.
Ames ACV Main Valves are Lead Free. The Ames ACV piloting
system contains Lead Free* components, ensuring all of our con-
figurations are Lead Free compliant.
