ABSTRACT:
A two-part coupling valve apparatus includes a first coupling part and a second coupling part which are mutually inter-engageable to open fluid communication through the coupling valve. The coupling parts can be disengaged from one another to discontinue fluid communication, which also closes fluid communication between each of the coupling parts and ambient. The retention volume of fluid exposed to ambient upon the coupling parts being disconnected is small. The coupling valve also allows a user to selectively regulate the flow rate of fluid by manually rotating the coupling parts relative to one another.
