6.2 Stroke And Range Spring Change
As a general rule it is most recommendable to prepare separate actuators for diffent
strokes and spring ranges to avoid modifications. However, modifications can be
done by using the parts mentioned below.
Of Models HA2 and HA3, there are two different diameters of bonnet connection
sections. For these models, note the following:
Of Model HA, modification for change between read stroke of 14.3 or 25mm and
that of 38mm cannot be done.
Of Model HA3, modification for change between rated stroke of 25 or 38mm and
that of 50mm cannot be done.
