| 1. A method of attaching and removing a nozzle having a liquid dispensing passage to a dispensing valve having a housing with
a nozzle mounting surface, a liquid supply passage opening to the nozzle mounting surface, and a nozzle clamping and ejecting
lever coupled to the housing, the method comprising:
positioning the nozzle adjacent to the nozzle mounting surface,
pivoting the nozzle clamping and ejecting lever to a first position to clamp the nozzle to the nozzle mounting surface so
that the liquid supply passage communicates with the liquid dispensing passage, and
pivoting the nozzle clamping and ejecting lever to a second position causing the nozzle clamping and ejecting lever to contact
the nozzle and move the nozzle away from the nozzle mounting surface.
