Adjustment Procedure
Pressure adjustment
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 A and 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.

Adjustment Procedure
Pressure 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.

Speed control
1. The cylinder speed is adjusted with knobs
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 C

same number of rotations.
Note 1) If the piston rod jerks, close knob
operation is achieved.
3. Speed adjustment for return stroke
The speed is adjusted with the flow valve.
Open knob D gradually until the required speed is achieved.
4. Be sure to tighten the lock nut after adjustment.
