Abstract

A body has a through bore with first and second ends and an intermediate disposed transverse bore extending through a side wall in fluid flow communication with the through bore. A flow control member with a first transverse bore is movably mounted on the body. The flow control member is movable from a first position in which the first transverse bore is aligned with the transverse bore in the body to form a fluid flow path therethrough to a container attached to one end of the body, and a second position in which the first transverse bore is offset from the transverse bore in the body to block fluid flow through the body. A septum, mounted in the second end of the through bore of the body, is piercable by a syringe to withdraw or inject quantities of gas from or into the container attached to the body. A clamp ring is mountable over the first end of the body and sealingly traps edges of the side wall of the container surrounding an aperture in the side wall of the container to sealingly attach the body to the container. Detents and mating projections are formed in the flow control member and the clamp ring to define the closed position of the flow control member. Mating projections and annular ridges on the flow control member and the clamp ring define the fluid flow open positions of the valve upon rotation of the flow control member.
