Abstract

An over-molded fluid control value for use in fluid delivery systems. An embodiment of the fluid control valve includes a rigid substrate having a opening defined therein, and a valve structure fabricated of an elastomeric material. The valve structure is over-molded over at least a portion of the rigid substrate and including a valve portion extending over the opening, the valve portion movable in response to a differential fluid pressure to allow fluid flow.
