CLA-VAL 100AF : Fuelling Drain Valve
The Cla-Val Model 100AF Drain Valve is a diaphragm actuated, hydraulically operated globe pattern valve. It is installed in the drain line from the water accumulator sump of FueVWater Separators. It is controlled by the Float Control valve which applies operating pressure above the diaphragm when the Fuelling Drain Valve is to close and relieves pressure to the atmosphere when the valve is to open. If diaphragm becomes damaged, valve closes tight.
