ABSTRACT:
A swing check valve having a generally cylindrical body with a fluid passageway extending therethrough, an annular resilient seat molded in place within said 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 a spring biased pivoting arm and a generally circular valve loosely mounted to the arm and adapted to engage the seal. The arm and valve are connected by a threaded fastener fixedly mounted to the valve and extending through an oversized aperture near the free end of the arm, and an adjustment nut. During assembly the free movement of the valve with respect to the arm is adjusted by rotating the valve and fastener with respect to the nut until the desired amount of movement is obtained and then welding this nut to the fastener. Any tendency of the valve to spin during operation is eliminated by the walls of a recess formed in the arm which prevent the adjustment nut, fastener and valve assembly from turning.
