ABSTRACT:
A fluid dispensing valve is made up of a plural part valve body enclosed by an elastomeric sheath sealed at spaced locations to the outside surface of the valve body. Fluid is dispensed out of a container through the dispensing valve. The arrangement of the valve body parts and the sheath permit flow out of the valve but prevent any flow back into the container. As a result contamination can not flow back through the valve into the container.
