HANDLING & STORAGE
HANDLING
Do not drop or throw the product as it may break.
STORAGE
Store away from dust, moisture and direct sunlight.
If possible, store in the original package.
CHECKING
• Check the product code, power supply, and voltage
before installation.
• Make sure that the bolts are not loose.
• The DIP switch should be set up before the power is
turned on. Do not touch unnecessary switches.

INSTALLATION
PRECAUTIONS
• Flush the pipeline carefully before installing the
valve. Foreign particles, such as sand or pieces of
welding electrode, will damage the disk and seats.
• When piping the valve disk should be closed before
mounting.
• Avoid oil or grease when using EPDM seat.
• The butterfly valve should be piped upstream of the
elbow. When piping downstream from the elbow,
considered a straight line that is at least five times
the length of the pipe.
• The valve stem should be mounted perpendicular to
the flow for biased fluid.
PIPING
• Using a pipe with too long a thread will damage the
valve.
• If sealing tape or sealant gets inside the valve, the
valve seat leaks or malfunctions.
• When connecting a pipe or fitting to a valve, use a
tool on the octagonal or hexagonal part of the
insertion side and screw it.
• Refer to the recommended tightening torque table
and do not apply excessive torque.
Valve size [mm] Torque [Nm]
015 25 to 35
020 40 to 50
025 50 to 60
032 60 to 80
040 75 to 85
050 90 to 110
Socket End
Should use adhesive suitable for valve materials.
ENVIRONMENT
• Do not install in place where corrosive gas is present
or where vibration is heavy (0.5 G or more).
• When radiant heat causes the surface temperature
of the control unit to exceed 55 °C (ACR: 50 °C),
provide an appropriate shielding plate.
• If there is a possibility that the fluid and drive part
freeze, please take measures to prevent freezing.
POSITIONING
Should be positioned through 90° upward from
horizontal. Provide space around the product to
allow manual operation, inspection and replacement
work.
Margin required around the actuator for maintenance
AM (030 / 070) DM2 (030) More than 65 mm
AM AH1 DM PAX ACR More than 90 mm
OTHER NOTES
Until the wiring is completed there must be no
condensation or flooding in the interior of the
actuator, after piping. Protective caps on the cable
gland are not waterproof.
WIRING
• Do not wiring outdoors on a rainy day.
• Check the power supply and voltage.
Connect the signal as shown in the wiring diagram.
• Do not connect unnecessarily terminal.
• Use suitable flexible cable (5 to 10.5 mm).
Lock and seal the cable completely to prevent
condensation inside the actuator.
• Built-in terminal block can clamp up to 1.5 mm² in
diameter without using solderless terminal.
• Allow proper cable slack for maintenance.
• Actuator should be electrically grounded.
Use the terminal marked ( ) inside the actuator.
PREVENT DEW CONDENSATION
• When installing the cover after wiring, perform the
bolt by the temporary tightening procedure and the
permanent tightening procedure to tightly and
securely tighten the rubber packing so that water
does not enter from the outside.
• Tighten the cable gland nut so that there is no
leakage from the wire entrance.
