ABSTRACT:
Similar transfer units are disclosed for launching pig balls into a pipeline and for receiving the pig balls from a downstream portion of the pipeline, each of the transfer units including a hollow housing providing an axially aligned manually or hydraulically operable valve member and valve seat for closing off a magazine which is inclined from horizontal to permit gravity transfer of the pig balls, the hollow housing being otherwise shaped to facilitate transfer of the pig balls. With a pair of the transfer units being connected with a pipeline, the launching unit includes controlled plungers for regulating passage of individual pig balls into the pipeline while the receiving unit at the downstream portion of the pipeline is arranged for directing the pig balls into the receiving unit. A magazine housing for each unit is separable from the hollow housing to facilitate replacement of the valve seat.
