Abstract
A check valve includes a valve housing and at least one control member. The valve housing includes a sidewall and an opening extending therethrough. The sidewall defines the opening and includes at least one recess formed therein. Each control member is rotatably coupled to the valve housing within the sidewall recess, and each control member is configured to allow flow of fluid through the valve opening in a first direction. Each control member is further configured to substantially prevent flow of fluid through the valve opening in a second direction that is opposite the first direction.
