Note: Removal of actuator only, will not alter the "set" maximum valve lift.

А весь пункт таков:

Setting 'maximum' valve lift
The maximum valve lift is factory set prior to despatch.
Should you wish to dismantle the valve for inspection or spares replacement, the maximum valve lift should be reset (see Section 4.3.1)
Note: Removal of actuator only, will not alter the "set" maximum valve lift.
Before setting 'maximum' valve lift, the valve should be isolated with both upstream and downstream pressures at zero.

Как перевести это самое примечание. Что-то не пойму, в чем смысл.
