ACV Schematic - Series LF985GD-20

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.
