A ball launcher having dual compartments for both launching and receiving a ball in which the compartments are oppositely directed. Seal means on the outside of each of the compartments for coacting with telescopic sleeves whereby the seals are isolated from fluid flow for preventing damage to the seals. A valve inlet and a ball insertion conduit both of which are removably connected to the valve housing for providing ease of access to the various valve seals. The seals on the dual compartments are supported from removable inserts for ease of repair and replacement. After the ball has been inserted into the dual launcher, the launcher may be rotated 90 degrees to dump the ball into the outlet, and the second compartment will be adjacent the inlet and is sealed off and used for catching the ball. The operation may be repeated by rotating the launcher 180 degrees.
