An adhesive dispenser is provided that includes a valve body, a valve block mounted for sliding movement along a surface of the valve body and an actuator assembly operative to move the valve block between open and closed positions. With the valve block in an open position, adhesive can flow through a supply passage, a first plurality of distribution passages in the valve body, and a second plurality of distribution passages in the valve block. The second plurality of distribution passages have first ends that open toward the valve body and second ends adapted to the dispense adhesive onto a substrate. When the valve block is in the closed position, the first and second pluralities of distribution passages are misaligned and adhesive is not dispensed.
