Operating principle
Working stroke Return stroke
1. The cylinder starts smoothly because jerks are prevented by
meter-in control. 3. To prevent delay due to the pressure gap, air is rapidly
exhausted to decrease the pressure from Dto 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.
2. When the cylinder reaches the stroke end, the quick air charge
by the flow valve rapidly increases the rear side pressure (PH)
from Ato 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.

Install a flow valve on the working side which requires the cylinder output and a pressure valve on the return side.The product cannot be
used in cases where the same pressure is necessary for both working and return strokes.
In such cases use a speed controller.

1. The cylinder speed is adjusted with knobs C, Dand E. First
have all the knobs fully closed and then open them gradually
for adjustment. Turn the knob clockwise to close (decrease the
speed of the piston rod) and counterclockwise to open
(increase the speed of the piston rod).
2. Speed adjustment for the working stroke
The speed is adjusted with the pressure valve and the flow
valve.
Open knobs Cand Egradually until the required speed is
achieved. Make sure that knobs Cand Eare opened by the
same number of rotations.
Note 1) If the piston rod jerks, close knob Euntil the smooth
operation is achieved.
3. Speed adjustment for return stroke
The speed is adjusted with the flow valve.
Open knob Dgradually until the required speed is achieved.
4. Be sure to tighten the lock nut after adjustment.

2. Speed adjustment for the working stroke
The speed is adjusted with the pressure valve and the dual

4. Be sure to tighten the lock nut after adjustment.
Adjustment Procedure 1
Pressure adjustment Speed control
Adjustment Procedure 2
1. The fixed set pressure type (-F20) does not require adjustment
because the pressure is fixed at 0.2 MPa for both the pressure
valve and the flow valve.
2. The set pressures of the variable set pressure type pressure
valve and flow valve are adjusted with knob Aand knob B
respectively. Turn the knob clockwise to increase the pressure
and counterclockwise to decrease the pressure.
3. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3
MPa respectively. Align the bottom end of the knob with the
graduated line for adjustment.
4. Set the same pressure for the pressure valve and the flow
valve (0.2 MPa as the recommended value).
5. The inlet side should be supplied with a pressure which is
higher than the set pressure by 0.1 MPa or more.
6. Cap the valve after adjustment.

1. The fixed set pressure type (-F20) does not require adjustment
because the pressure is fixed at 0.2 MPa.
2. The pressure at the low pressure side (return stroke side) is
adjusted by the pressure valve.
3. The set pressure is adjusted with knob A. Turn the knob
clockwise to increase the pressure and counterclockwise to
decrease the pressure.
4. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3
MPa respectively. Align the bottom end of the knob with the
graduated line for adjustment.
5. Keep the set pressure as low as possible in order to achieve
good air saving effect.
6. Cap the valve after adjustment.
