A valve for use in a subterranean drilling string or casing string comprising: a tubular housing comprising an inner surface and a bore for fluid flow inside the tubular housing ; a ball comprising an internal bore and a rounded external contour, wherein the ball is sized to rotate within the tubular housing ; at least one pilot located inside the internal bore of the ball , wherein the at least one pilot permits fluid flow in one direction; a seat located along the bore of the tubular housing , wherein the seat prevents fluid flow between the ball and the tubular housing ; and a pusher rod attached to the tubular housing with a compressible spring , the pusher rod comprising a cylindrical shape, a first end , a second end , at least one seal , and an internal bore connecting the first end and the second end , wherein the first end and the second end each comprise an opening , wherein the internal bore comprises an internal diameter, wherein the first end opening is angled outward with the internal diameter increasing toward the opening and the second end opening is angled outward, wherein the internal diameter of the second end opening substantially matches a corresponding exterior contour of the ball , wherein the second end is rounded to substantially match the corresponding exterior contour of the ball , wherein rotation of the internal bore of the ball away from the internal bore of the pusher rod prevents fluid flow through the internal bore of the ball , and rotation of the bore of the ball towards the internal bore of the pusher rod permits fluid flow in the one direction through the internal bore of the pusher rod and the internal bore of the ball , characterized in that compression of the spring by the pusher rod creates a bypass space along the inner surface of the tubular housing permitting fluid flow around the pusher rod and within the inner surface of the tubular housing . a tubular housing comprising an inner surface and a bore for fluid flow inside the tubular housing ; a ball comprising an internal bore and a rounded external contour, wherein the ball is sized to rotate within the tubular housing ; at least one pilot located inside the internal bore of the ball , wherein the at least one pilot permits fluid flow in one direction; a seat located along the bore of the tubular housing , wherein the seat prevents fluid flow between the ball and the tubular housing ; and a pusher rod attached to the tubular housing with a compressible spring , the pusher rod comprising a cylindrical shape, a first end , a second end , at least one seal , and an internal bore connecting the first end and the second end , wherein the first end and the second end each comprise an opening , wherein the internal bore comprises an internal diameter, wherein the first end opening is angled outward with the internal diameter increasing toward the opening and the second end opening is angled outward, wherein the internal diameter of the second end opening substantially matches a corresponding exterior contour of the ball , wherein the second end is rounded to substantially match the corresponding exterior contour of the ball , wherein rotation of the internal bore of the ball away from the internal bore of the pusher rod prevents fluid flow through the internal bore of the ball , and rotation of the bore of the ball towards the internal bore of the pusher rod permits fluid flow in the one direction through the internal bore of the pusher rod and the internal bore of the ball , characterized in that compression of the spring by the pusher rod creates a bypass space along the inner surface of the tubular housing permitting fluid flow around the pusher rod and within the inner surface of the tubular housing . <EOS>
