CFF21 Flanged Float 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. 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 water level cannot be reduced by the drain valve, the float control signals the fuel discharge valve to close until the water has been drained.
