1. A catheter assembly comprising a catheter hub having a catheter tube extending from a distal end thereof, a needle hub having a needle extending from a distal end thereof and extending through the catheter hub in a ready to use position, and a valve located inside the catheter hub, the valve comprising:
a first side having a first surface defining a first plane having a first portion and having a second portion on the first side recessed from the first plane;
a second side having a second surface opposing the first surface and defining a second plane, the first surface and the second surface defining a thickness of the valve;
a plurality of slits extending from the first side to the second side of the valve at the second portion, the plurality of slits defining a plurality of flaps with each of the plurality of slits having an inward-most slit point and a radially outward-most point and wherein an imaginary arc connects the radially outward-most points of the plurality of slits to define a circular boundary;
at least two ribs on the first side, each of said at least two ribs having an exterior surface located on the first plane and extending from a point outside the circular boundary into the circular boundary;
a valve actuator slidably disposed inside the catheter hub, said valve actuator having an actuator head with a surface for pushing into the valve to deflect the flaps when a surface on a plunger end of the valve actuator is pushed by a connector tip inserted into the catheter hub in a used position; and
wherein the first surface defining the first plane extends radially outwardly of the exterior surface of each of the at least two ribs.
