ABSTRACT:
A swing check valve having a generally cylindrical body with a fluid passageway extending therethrough, an annular resilient seat molded in place within the passageway and oriented normal to the passageway axis and a clapper assembly pivotally mounted for rotation about an axis normal to the passageway axis. The clapper assembly includes an arm removably connected to a shaft extending through the body and a generally circular valve loosely mounted to the arm and adapted to engage the seal. The shaft is disposed for rotation within a bore extending completely through the body and a lever is removably attached to the external end of the shaft to permit manual operation of the valve. In order to prevent the valve from slamming shut in the event of a sudden flow reversal, it is spring biased toward a closed position with a spring attached to the lever. The check valve can be easily converted from right to left hand operation or vice versa by removing the lever from the shaft, loosening the clapper arm, reversing the position of the shaft in the body and reinstalling the lever.
