Abstract
Disclosed is a valve engageable with an instrument, where the valve includes a deformable stem located in a valve body and shiftable from a first position. When an instrument is engaged with an aperture in the stem, the stem is urged from the first position into the valve body and the aperture deforms to allow liquid to flow through the stem, to or from the instrument. The stem and the valve body are configured such that when the instrument is not engaged with the stem, the valve body engages the stem and urges the aperture closed.
