Check valves are disclosed and include a housing defining an internal cavity having a first seat and a second seat, and a seal member within the internal cavity translatable between a closed position against the first seat and an open position against the second seat. The second seat has a middle axis transverse to a plane of a longitudinal cross-section of the housing and has a shortest finger positioned to either the left or to the right of the middle axis. The seal member is seatable against the second seat at an angle or in a deflected position against the plurality of fingers, thereby defining a longer distance of travel to reach the closed position for a portion of the check valve disc that is associated with the position of the shortest finger relative to other portions of the check valve disc.
