Abstract
A lever float valve comprising a float stem with a central vertical axis; a float body coupled to the float stem and rotatable relative to the central vertical axis of the float stem; a valve segment positioned within the float body and configured to pivot around a first axis perpendicular to the vertical axis; and a lever comprising a float arm and a float coupled to the valve segment and configured to pivot around a second axis perpendicular to the vertical axis.

A lever float valve comprising:
- a float stem with a central vertical axis;
- a float body coupled to the float stem and rotatable relative to the central vertical axis of the float stem;
- a valve segment positioned within the float body and configured to pivot around a first axis perpendicular to the vertical axis;
- and
- a lever comprising a float arm and a float coupled to the valve segment and configured to pivot around a second axis perpendicular to the vertical axis;
- wherein, in operation, the valve segment rotates around the first axis to open and close a first valve aperture and the lever rotates around a second axis to open and close a second valve aperture.
