The Cla-Val Model CFF18T-H2 Fuel-Water Separator Control
automatically operates the fuel discharge valve and the water drain
valve of fuel-water filter separators. It is mounted to a flange on the
side of the separator vessel in the sump. The float responds to
changes in level of the interface surface of the water and fuel inside
the sump area. The pilot valve is a precision-lapped rotary disc, plate
type valve. The CFF18T-H2 Control automatically performs the
following functions:
1. Opens the water drain valve (Model 100AF) to remove
accumulated water that exceeds the safe level in sump area.
2. Closes the fuel discharge valve (Model 413-01 or 40-28 AGS)
should the water level rise to the upper float level. The water drain
valve remains open.
3. Re-opens the fuel discharge valve when the water in the sump
lowers to a safe level.
4. Closes the water drain valve when the level reaches a low point in
the sump.
5. Provides easy manual testing of fuel-water separator control
function with simple plunger-type mechanism spring loaded to return
to normal operating position.
The CFF18T-H2 Control is used with aviation gasoline, jet fuels,
motor fuels, diesel, solvents and other petroleum products. This
control has a variable pressure rating depending on lever arm length
and is suitable for handling liquids with a specific gravity of 0.90 or less.
