Abstract
An apparatus for restricting fluid flow includes: a ball receiving element disposed in a first fluid conduit and configured to receive a ball that has been advanced through the first fluid conduit and at least partially restrict a fluid flow in the first fluid conduit; and at least one second fluid conduit in fluid communication with the first fluid conduit at an upstream location relative to the ball receiving element, the at least one second fluid conduit configured to divert a portion of the fluid from the first fluid conduit and reduce an impact between the ball and the ball receiving element.
