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 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.
