A fluid delivery system for delivering a fluid from an automatic water source to animals housed in cages in high density caging systems may comprise a fluid delivery valve assembly, wherein the fluid delivery valve assembly is adapted to be coupled to the automatic water source to facilitate the provision of fluid to animals housed in the cages. The fluid delivery valve assembly may further comprise a valve body and end cap, which may be joined together, that define a fluid channel. The fluid delivery valve assembly may further comprise sealing elements, a spring element, and an interior stem disposed at least in part in the fluid channel to open and close the fluid channel.

1. A valve assembly for delivering a fluid from an automatic water system to a cage in an animal caging system for housing one or more animals, comprising: a valve body and an end cap joined together with a first sealing element therebetween to define distal and proximal portions, respectively, of a fluid channel through the valve assembly; anda spring element, an interior stem, and a second sealing element disposed within the valve body and the end cap and in the fluid channel to open and close the valve assembly,wherein the valve body and the end cap comprise injection molded plastic and are formed with complementary features on their mating ends, said features configured to interlock when the valve body and the end cap are snap fit together, andwherein the interior stem comprises an injection molded plastic stem body having an enlarged top portion and an elongated lower portion, and a stainless steel insert pin disposed within the stem body and extending beyond the lower portion, forming a stepped structure whereby a lower surface of the lower portion of the stem body abuts a lower shoulder of the end cap, and only a portion of the stainless steel insert pin is exposed to the cage for actuation by an animal therein. 2. The valve assembly of claim 1, wherein the injection molded plastic forming the valve body, the end cap, and the stem body comprises polyphenylsulfone. 3. The valve assembly of claim 1, wherein said features comprise one or more protruding rings around a circumference of the valve body. 4. The valve assembly of claim 1, wherein said features comprise one or more openings around a circumference of the end cap. 5. The valve assembly of claim 1, further comprising a replaceable micron-level water filter positioned within the valve body at a distal end of the fluid channel therethrough. 6. The valve assembly of claim 5, wherein the filter has a three-dimensional shape. 7. The valve assembly of claim 5, wherein the filter has a substantially cylindrical shape. 8. The valve assembly of claim 1, further comprising a non-removable stainless steel valve shield covering the valve body and the end cap and held permanently in place on the valve body by a crimp in the metal. 9. The valve assembly of claim 8, wherein the valve shield comprises identifying information engraved or etched thereon. 10. The valve assembly of claim 1, wherein the valve assembly is configured to be mounted to the cage. 11. The valve assembly of claim 10, further comprising a valve stem for mounting the valve assembly into an air grommet in a sidewall of the cage, wherein the valve stem comprises: a proximal end comprising screw threads for connecting to the valve assembly;a distal end comprising an elongated portion for connecting to a quick disconnect (QD) element; anda peripheral flange between the proximal end and the distal end forming an air baffle at the grommet to prevent non-sterile air from entering the cage when the cage is detached from the caging system,wherein the proximal end, the distal end, and the peripheral flange comprise a unitary body formed of injection molded plastic. 12. The valve assembly of claim 11, wherein the proximal end of the valve stem further comprises at least two injection molded plastic elements permanently molded thereto, including an alignment element molded at a distal end of the screw threads and a sealing element molded at the proximal end of the screw threads. 13. The valve assembly of claim 12, wherein the sealing element is molded into an undercut in the proximal end of the valve stem. 14. The valve assembly of claim 12, wherein the proximal end, the distal end, and the peripheral flange of the valve stem are formed in a first mold and moved to a second mold, and the alignment element and the sealing element are molded thereto in the second mold. 15. The valve assembly of claim 12, wherein the proximal end, the distal end, and the peripheral flange of the valve stem are formed via a first injection in a mold, and the alignment element and the sealing element are molded thereto via a second injection in the mold. 16. The valve assembly of claim 1, wherein the valve assembly is configured to be mounted to the automatic water system manifold. 17. The valve assembly of claim 16, wherein the valve assembly is configured to be mounted to the automatic water system manifold via a quick disconnect (QD) element.
