A fill valve assembly comprises a valve body extending along a longitudinal axis and defining a fluid inlet, a valve seat and at least one fluid outlet, an axially slidable valve element arranged for axially slidable movement along the longitudinal axis, into and out of sealing engagement with the valve seat, the axially slidable valve element defining a first upstream conical surface having a first surface area and a second downstream conical surface having a second surface area, greater than the first surface area, and a fill sensor operative below a predetermined fill threshold to prevent the axially slidable valve element from establishing sealing engagement with the valve seat
