- the valve housing (300)

There are six balls in the valve housing. 4 small (372) and 2 larger (373).
When separating the valve housing from the control system housing: The gaskets and plate must remain in the valve housing so that the balls do not fall out of their seats in the valve housing.

2 plastic plugs (368) hold the gasket and plate in place.
