1. The cylinder starts smoothly because jerks are prevented by
meter-in control.

Return stroke
2. When the cylinder reaches the stroke end, the quick air charge
by the flow valve rapidly increases the rear side pressure (PH)
from A to B. If a speed controller is used instead of the flow
valve, charging air will take more time as illustrated by line A-
C, causing delay in the pressure rise.

3. To prevent delay due to the pressure gap, air is rapidly
exhausted to decrease the pressure from D to E, after which
the piston moves at a constant speed. If a speed controller is
used instead of the flow valve, exhausting air will take more
time as illustrated by line D-F, resulting in longer stop time of
the cylinder and a consequent time loss.
4. The cylinder operates at a low pressure required for a return.
