How the Amtrol FILL-TROL 111 Expansion Tank System Works:
Water enters the FILL-TROL valve, pushing open the check valve, and flows into the heating system. The automatic shut-off valve is kept open by the diaphragm pressing against the pressure plate, raising the stem of the fill gate, which compresses the automatic shut-off valve spring. When the heating system reaches fill pressure (12 psig), the tank's diaphragm depresses, and the automatic shut-off valve is closed.

Whenever system pressure falls below 12 psig, the automatic shut-off valve is pressed open by the diaphragm. Make-up water flows into the system to restore pressure.
