A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, and a rotating member with a member channel. The rotating member is rotatable to cause the valve to transition from the closed mode to the open mode after insertion of a medical implement into the inlet. The member channel fluidly communicates the inlet and the outlet when in the open mode. The medical valve also has a resilient member biasing the rotating member toward the closed mode. The rotating member slides along the resilient member when rotating between the open mode and closed mode.
