An applicator for application of a substance onto a material. The applicator has a housing, a valve and a nozzle. The applicator may also have a journal that is connected to the valve which together translate in a linear motion to provide shuttering functionality. The valve may be circular or non-circular in shape. The applicator may extrude hot-melt onto a continuous web or drum. In another embodiment, the applicator may have a housing and a valve.
