During any stabilised running condition, the spill or half ball valve is
- always varying between fully closed and fully seated.
- lightly seated.
- open fully.
Explanation from PART66Online
Under any steady running condition the spill (half-ball) valve bleeds off just the small surplus of pump delivery needed to hold the metered flow constant, so it floats lightly on its seat. It is not fully closed or fully open - it sits lightly seated and modulates around that position.
