Abstract
This invention relates to a flat ball valve coupling that reduces spillage to less than 1CC. The coupling provides numerous safeguards against spillage because one of the flat ball valves rotates and pulls away from the other flat ball valve. This eliminates any spacing between the flat ball valves in the closed position thereby eliminating spillage during uncoupling. Another feature is an interlock which prevents the coupling from being accidently disconnected when either valve is open.
