The “pancake” type may discharge the fluid from the check valve nozzle in a perpendicular, forward, or rearward direction. The check valve nozzle assembly contains a number of check valve nozzles that can vary in size, orientation with respect to the longitudinal centerline of the end cap of the assembly, and/or construction materials.
