FILL-TROL, a specially designed, automatic, pressure-reducing fill valve.

• Provides accurate system make up

• Eliminates need for a separate, automatic fill valve

• Fully adjustable up to a maximum working pressure of 100 psig

• Factory pre-charged to 12 psig; tank pressure controls system fill

How the FILL-TROL 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.
