3. The spray system of claim 1 , wherein at least two of the distribution conduits are simultaneously fluidly engaged to the arcuate aperture as the rotary distribution block rotates relative to the fixed distribution block.

4. The spray system of claim 1 , further comprising at least two spray bar assemblies, each spray bar assemblies mounted such that the rotary cages are in parallel relation.

5. The spray system of claim 1 , further comprising at least two spray bar assemblies, wherein the arcuate apertures of the at least two spray bar assemblies have differing angular outlet ranges.

6. The spray system of claim 1 , wherein the rotary distribution block causes the pressurized fluid supply to be dispensed from the spray nozzles in only a downward trajectory as dictated by the arcuate aperture.

7. The spray system of claim 1 , wherein the pressurized fluid comprises at least one peroxycarboxylic acid having between about 2 to 12 carbon atoms.

8. The spray system of claim 1 , wherein the rotary distribution block is rotated by the means for rotating at a rate of between about 10 rpm to about 100 rpm.

9. The spray system of claim 1 , wherein the means for rotating is selected from the group consisting essentially of: a motor directly coupled to the rotary cage, a belt drive assembly, a chain drive assembly and a gear assembly driven by a motor.

10. A method of spraying items, comprising:

supplying a pressurized fluid to a distribution valve, said distribution valve including a fixed distribution block and a rotating distribution block, wherein the pressurized fluid is directed into an arcuate aperture on the fixed distribution block;

rotating the rotating distribution block relative to the fixed distribution block such that a plurality of distribution conduits defined in the rotating distribution block are sequentially introduced to the arcuate aperture;

directing the pressurized fluid through each distribution conduit when each distribution conduit is fluidly engaged with the arcuate aperture, each distribution conduit being fluidly coupled to a linear distribution manifold, wherein the linear distribution manifold defines a rotary cage that rotates in conjunction with the rotating distribution block; and

spraying the pressurized fluid from a plurality of spray nozzles on each linear distribution manifold when the corresponding distribution conduit is fluidly engaged with the arcuate aperture.
