Level Control for Filter Separators
Cla-Val Level Control
The Cla-Val Model CFF21 Flanged Float Control is a float operated pilot control installed in the water accumulation sump of a fuel filter/separator in an aviation fueling system. It is designed to automatically actuate a water drain valve (Model 100AF) and to sense a rapid accumulation of water in the sump in excess of the capacity of the drain valve. If the drain valve cannot reduce the water level, the float control will signal the fuel discharge valve to close until the water has been drained.
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.
