Abstract
A tank valve for maintaining a water lever storage level in a tank. The tank valve includes differential pressure valve workings under control of a pivot member. A float enables the valve to open when resting on the pivot member and opens the valve when it rises free of the pivot member. A boost link depends from the pivot member to be boosted by the float near the end of its upward travel to assure closure of the valve working when an intended water level has be attained.
