Ambient and fluid temperature
Applicable tube materials
Note1: Pay attention to the maximum operating pressure for soft nylon and polyurethane.
Note2: For AKP-*-M5/U10 pilot check valve, pressure must be more than 50% of operating pressure and
0.15 MPa or more.
5. Malfunctions and Countermeasures
Trouble
Actuator is Unable
to reach an
intermediate stop
position.
Air leaks from the
One-touch fitting.
Or the tubing
disconnects.
(note 1)
Possible causes
The
piping
orientation
incorrect.
Dust inside.
The
residual
pressure
exhaust
button
has

to
the
position.
Tubing has been cut using
pliers or nipper.
The tolerance of the outside
diameter of the tubing in use
is beyond the specification.

is
Connect the IN (port 1, port 21) side to the
directional control valve, and OUT (port 2) side to
the actuator.
Conduct air blow from the port 1 (IN) side.
A foreign matter may be attached to the valve.
If the condition does not improve even after air
blow, install an air filter to the piping, and replace
the product with a new one.
If the button has not returned to the end face of the
not
product, the product may have failed. Replace the
normal
product with new one.
Use tube cutters.
When using a tubing other than from SMC, confirm
that the tube material and the O.D. accuracy satisfy
the following specifications.
1) Nylon tube
2) Soft nylon tube
3) Polyurethane tube +0.15 mm at max.
