A snap-action piloted fill valve for controlling the level in a liquid storage tank, the valve having a float and a weight cup that are adjustably interconnected by an elongated sleeve slidably disposed on a stem extending upwardly from a valve body mounted inside a tank, the weight cup being further connected to a snap-action beam attached to the valve body. The snap-action beam controls operation of a pilot, which in turn causes the fill valve to open when the beam is in its upward position and to close when the beam is in its downward postion. Use as a toilet valve is also disclosed.
