ACV Schematic - Series LF981GD

This Ames Automatic Control Valve (ACV) is a full port, single

chamber basic valve that incorporates a one-piece disc and dia-

phragm assembly. This assembly is the only moving part within

the valve allowing it to open, close, or modulate as commanded

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.
