A valve assembly includes a receptor valve assembly having a normally closed fluid passage, and an insert assembly having an open fluid passage. The insert assembly and the receptor valve assembly each include a valve activation structure engageable with one another for opening the fluid passage of the receptor valve assembly upon engagement of the valve activation structures and rotation of the insert assembly relative to the receptor valve assembly wherein their fluid passages are interconnected. The insert assembly and the receptor valve assembly are configured to provide substantially no fluid passage therebetween when closed.
