Control System Housing

There are 4 more balls in the control system housing. See Fig 1. The balls will fall out when the valve housing is removed. Collect the balls in a clean container (the balls will be reinstalled later). There are 2 balls which do not fall out when the valve housing is removed (these are in the control system, C1 and C2).
