The specified positioning times refer to the respective nominal stroke / nominal
angular rotation. Since the end positions of rotary actuators are inside the actuator,
the following remarks refer to stroke actuators.
The resulting effective strokes vary, depending on the type of valve, resulting in
shorter or longer actuator positioning times.
Stroke of valve-actuator combination [mm]

X Time to override idle stroke (delay time), see glossary
Deviations occur
· after several positioning signals Y1 and Y2 in the same direction since the stroke
movement starts with a delay of 50 ms.
· when positioning signals Y1 and Y2 are active for less than 50 ms since the
stroke movement cannot be made in that case.
