KTM PNEUMATIC ACTUATORS - AW, AWN SERIES
INSTALLATION AND OPERATION MANUAL
6. When using the actuators outdoor in cold
or snowy areas moving parts of accessories
(positioner, limit switches, etc.) may be
frozen. Protect the devices by proper
covering in such cases.
7. When installation orientation of actuator is
changed for convenience of positioning, the
following caution should be taken.
1. Exhaust port of the actuator and
accessories (solenoid valve, air operate
valve, quick exhaust valve, etc.) should be
directed downward by attaching elbows.
If doing so is difficult due to surrounding
area environment, use elbow for
exhausting downward.
2. Since attaching orientation of filter
regulator or lubricator is limited, drains
should be directed downward.
CAUTION
Do not position single acting torque cylinders in
such orientation that springs are facing upward.
By doing since, the inside of the cylinder may be
corroded by entering of water, which may cause
malfunctions.
8. In piping for operating actuator work, care
should be taken as follows.
1. Clean joint and tubing sufficiently by using
compressed air before piping.
2. When sealing tape is used, apply tape to
thread starting two threads back from
end of fitting in order for the fragments of
the tape not to enter inside of the pipe.
3. Since copper tubes are regularly used for
connecting accessories, avoid vibrational
place for installing. In severe vibrational
environments, use Nylon tubing.
(The copper tube loosen by vibration may
cause leakage.)
4. Do not tighten the joint excessively to the
supply port of the actuator.

CAUTION
Excessive fastening of joint may cause cracking of
supply port leading air leakage.

accessories Schematic diagrams of piping
