摘要: Multiple ball launch assemblies comprise a plurality of pods disposed around an outer wall surface housing. The are operatively associated with flow tube within the An actuator assembly rotates to align first opening in pod so that is launched into wellbore. Further rotation aligns subsequent openings corresponding balls
