Abstract
A check valve comprises a valve housing defining an unobstructed valve opening and a pair of flapper elements each having a proximal end and a distal end. The flapper elements are pivotally mounted to the valve housing at opposed sides of the valve opening at their proximal ends for pivotal movement between a closed position, in which together they block the flow of fluid through the valve opening and an open position in which they permit the flow of fluid through the valve opening. The valve further includes a bumper element arranged at the proximal end of each flapper element for engagement with the valve housing when in the open position for limiting the angle of rotation of each flapper element.
