4-3 Adjustment of valve position
<Full-close position adjustment procedure
(Full-close side adjustment)>
(1) Set position to open on this product. Check that
the position indicator㉑ indicates O (Open).
(2) Remove the air pipelines and set inside pressure
to atmosphere.
(3) Release the hexagon nut 󱞹.
(4) Use a hexagonal wrench to rotate the hexagon
stop screw 󱞻 to the required angle. The hexagon
stop screw 󱞻 is rotated clockwise, and the valve
full-close position becomes shallow. Please refer
to [Table 1] for rotation angles.

Single-acting type cylinder (7F)
For pressure-closing single-acting type cylinders
(7F), the opening adjustment position is different
from this figure. Perform the full opening side
adjustment by adjusting the bolt at the [OPEN]
side of the base plate. The tightening torque
should be the torque of "Closing side stopper bolt"
in [Table 2] for both the open and close sides.
Do not release the hexagon nut 󱞸 and the hexa-
gon stop screw 󱞺 to prevent danger. [Fig. 4]

<Full-open position adjustment procedure
(Full-open side adjustment)>
(1) Set position to close on this product. Check that
the position indicator ㉑ indicates Close.
(2) Remove the air pipelines and set inside pressure
of the product to atmosphere.
(3) Release the hexagon nut 󱞸. [Fig. 3]
(4) In case of deformation or breakage of the seal
washer 󱟁, replace it with a new seal washer.
Otherwise, air leakage may occur.
(5) Use a hexagonal wrench to rotate the hexagon
stop screw 󱞺 to the required angle. The hexagon
stop screw 󱞺 is rotated clockwise, and the valve
full-open position becomes shallow. Please refer
to [Table 1] for rotation angles.
<How to restore after adjustment>
(1) Hold the hexagon stop screw 󱞺 or 󱞻 in position
with a hexagonal wrench, and tighten the hexagon
nut 󱞸 or 󱞹 with a spanner. Please refer to [Table
2] for the tightening torque.
(2) Apply air pressure to the cylinder and check that
the rotation angle of the output shaft is obtained,
and there is no air leakage.
(3) If readjustment is required, repeat the above
procedure from (1).
Note) Full-close/full-open position is adjusted when
shipped.
