<p>A two-part coupling valve apparatus includes a first and second coupling part (42, 78), each coupling part including a valve member (58, 158). The valve members (58, 158) have respective valve seats (52d, 152d) including camming surfaces (60a, 160a). The respective camming surfaces of the valve members engage one another and relatively rotate upon relative rotation of the coupling parts to axially unseat each valve member from its respective valve seat.</p> |
