Abstract
A method of assembling a valve assembly for delivering a fluid from a fluid bag to an animal caging system for housing an animal can include coupling an upper member having a piercing member to a base having a base fluid channel. The method can also include disposing a stem member at least partially within the base fluid channel and disposing a sealing member in the base fluid channel. The sealing member preferably has a flow aperture and a sealing member bottom surface, and facilitates sealing of the flow apertures when the sealing member bottom surface abuts a top surface of the stem member. The method can further include disposing a spring element within the base fluid channel, wherein a portion of the spring element abuts the lower surface to apply a biasing force to the stem member.
