Abstract: A quick-connect coupling includes a male half and a female half, where the female half includes a locking mechanism to couple the male half to the female half; and a valve assembly, which when the male half is coupled to the female half, opens a flow path through the coupling. The valve assembly includes an upstream, pressure balanced secondary valve and a downstream primary valve. The secondary valve maintains the downstream portion of the female coupling half at zero pressure, such that the male half can be easily connected.
