The threshold and full stroke modulating pressures
come in three ranges, as shown above. The threshold
(the amount of differential pressure necessary to move
the actuator spool) and full stroke (the amount of
differential pressure necessary to yield maximum
swashplate displacement) ranges should be chosen so
as to be compatible with the hydraulic signal from the
command source, which is usually a control handle.
The full stroke figures shown are nominal. "02" and "03"
models use a spacer plate which makes the body
longer, as shown in Figure 1.
