ABSTRACT:
A fill valve has a main valve with a valving surface contacted by a valve disk. A series of offset radial paths separated by a toroidal path permit free radial flow at full open and quiet tortuous flow as the valve closes. Removal of a cap permits access to the main valve for cleaning. Indicia in the valve body provide easy height adjustments. A riser base is made up of easily molded locking parts and provides a variable height adjustment structure that is shielded from view. A flexible cup performs multiple functions including serving as a pilot valve, a vacuum breaker valve and a seal. A float for operating the pilot valve is pivotally mounted without extra parts or fasteners.
