VALVE SPEED
data length 6 characters starting with double zero for writing

xxxx valve
speed,
1 ... 1000 (1 = min. speed, 1000 = max. speed)
This command allows changing the actuating speed of the valve plate. Speed selection is
effective for pressure control and position control. Open valve and close valve are always
done with max. speed.
Note: Refer to «Valve speed adjustment» for details.
