A connector is described which includes a valve housing comprising a valve housing base and a valve cap, the valve housing defining an inlet port, and an outlet port, the valve housing further including a fluid path from the inlet port to the outlet port, the fluid path including a channel formed in an inner wall of the valve housing. A valve insert in the valve housing defines a bowl sealed by a diaphragm, such that the sealed bowl forms an inner volume in the valve housing. A valve plug operable seals the inlet port when the connector is in an unactuated state thereby closing the fluid path through the connector. Upon actuation of the connector the valve plug deforms the diaphragm into the inner volume thereby unsealing the inlet port and opening the fluid path through the connector. Because of the arrangement of the valve plug, valve insert and diaphragm, the connector has a low priming volume and has positive fluid displacement characteristics upon actuation.

What is claimed is: 1. A connector comprising:a valve housing comprising an inlet port, an outlet port, an inner wall, and one or more channels in the inner wall forming a fluid path from the inlet port to the outlet port;a valve plug operable to seal the inlet port when the connector is in an unactuated state thereby closing the fluid path through the connector;a diaphragm disposed within the valve housing; anda valve insert disposed within the valve housing, the valve insert comprising a bowl sealed by the diaphragm forming an inner volume, the valve insert further comprising a stem extending into the outlet port, the stem configured such that a cross-sectional flow area of the outlet port is approximately equivalent to a cross-sectional flow area of the flow path formed by the one or more channels in the inner wall of the valve housing;wherein upon actuation of the connector the valve plug deforms the diaphragm into the inner volume thereby unsealing the inlet port and opening the fluid path through the connector.
