WARNING:
• The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their
compatibility for the specific pneumatic system must be based on specifications or
after analysis and/or tests to meet your specific requirements.
• Only trained personnel should operate pneumatically operated machinery
and equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly,
handling or repair of pneumatic systems should be performed by trained and
experienced operators.
• Do not service machinery/equipment or attempt to remove components
until safety is confirmed.
Inspection and maintenance of machinery/equipment should only be performed
after confirmation of safe locked-out control positions.
When equipment is to be removed, confirm the safety process as mentioned
above. Switch off air and electrical supplies and exhaust all residual compressed
air in the system.
Before machinery/equipment is re-started, ensure all safety measures to prevent
sudden movement of cylinders etc. (Bleed air into the system gradually to create

Compact Direct Operated 3 Port solenoid valve
CAUTION: Operator error could result in injury or equipment damage.
WARNING: Operator error could result in serious injury or loss of life.
DANGER: In extreme conditions, there is a possible result of serious
injury or loss of life.
Body ported mounted, stacking type, barb fitting
Note: If other manufacturers' fittings are used with the base-mounted bar manifold,
please follow the appropriate fitting specifications.
Tube fitting
Cut the required length of tube at right angles to the tube axis (use tube cutter TK-
1, 2,3). Allow sufficient excess length.
Fit the tube up to the far end of the barb. If the tube is not completely fitted over
the barb, air leaks may result, and the tube could become detached.
When fitting the tube onto the barb fitting, insert it up to the end of the barb in a
direction parallel to the tube axis, to avoid placing excessive lateral force on the
barb fitting.
When removing a tube from a barb fitting, take care not to exert excessive lateral
force on the barb fitting. If a cutter is used to remove a tube, take care not to
damage the barb fitting.
After fitting, the tubes should not be subject to excessive loads caused by pulling,
compressing or bending.
3.3 Electrical connection
CAUTION:
When DC power is connected to a solenoid valve equipped with light and/or surge
voltage suppressor, check for polarity indications.
For polarity indications:
No diode to protect polarity: if polarity connection is wrong, the diode in the
valve or switching device at control equipment or power supply may be
damaged.
With diode to protect polarity: if polarity connection is wrong, the valve does not
switch.
CAUTION:
Internal wiring
Electrical circuit
Use electric circuits that do not produce any contact chattering.
The voltage should be within 10% of the rated voltage. If the rated voltage is less
than 6 V DC and response is an important factor, voltage drops should be taken into
consideration.
When a C-R component (surge voltage protector) is used to protect the switching
element, be aware that the leakage voltage is increased because of the leakage
current flowing through the C-R components. Limit the residual leakage voltage to
2% or less of the rated voltage.
Make sure that the correct voltage is applied, to avoid malfunction or coil burnout.
Arrange the lead wires so that excessive force is not exerted on them. This will
avoid coil rupture.

3.4 Mounting/Removal
CAUTION:
Body-ported, single unit
To fix a body-ported single-unit solenoid valve, fix the valve body as shown in the
diagram below and tighten the special screws (AXT632-106A-2) to the correct torque
(0.05 to 0.07 Nm). Do not apply excessive force to the coil, or when fitting the
tubes, as this could cause damage. Care should also be taken not to apply excessive
force to the coil section of base-mounted solenoid valves.
Base mounted with screws
For this type, ensure that a gasket is fitted between the valve and the manifold, and
tighten the special mounting screws (AXT632-106A-1) securely to the correct torque
(0.10 to 0.14 Nm).
Base mounted with clips
To install, insert a small flat-blade tip screwdriver into the hole in the mounting
bracket, pull it out by approximately 1 mm (in the direction (1) shown in the
diagram), and install the solenoid valve from above (2), so that it is mounted on the
interface. When the base of the solenoid valve meets the upper surface of the
manifold, press down the body of the solenoid valve and remove the screwdriver
from the mounting bracket. Ensure that a valve body interface gasket is installed.
An internal leaf spring returns the mounting bracket to its original position. Check
that the end surface of the mounting bracket is now flush with the side of the
manifold block (refer to the diagram below).
Similarly, to remove the valve, pull out the mounting bracket and lift the valve
directly upwards. When installing or removing, be careful not to exert excessive
force on the lead wires.
Extending or Shortening Procedures
Base-mounted, stacking type.
(1) Remove the clip and the metal joint of the parts to be extended in the
direction of the arrows (1) and (2), as shown in the diagram.
(2) Add an expansion manifold block assembly, and attach the metal joint and
clip in reverse order to their removal. The clips should be securely inserted so
that they do not protrude from the top surface of the block, and the metal joints
should not protrude from the bottom surface. The clips are used to fix both the
manifold block and the fitting.
Body-ported type
(1) Remove the clips from the parts to be extended, in the direction of the arrow
shown in the diagram. (Insert a flat-blade tip screwdriver into the recess shown
in the lower diagram.)
(2) Add an expansion solenoid valve to the separated parts, and insert the clips
in reverse order to their removal. Insert each clip securely until it reaches the
stopper on the side of the body.
3.5 Lubrication
CAUTION:
SMC products have been lubricated for life at manufacturer, and do not require
lubrication in service.
If a lubricant is used in the system, use turbine oil Class 1(no additive), ISO VG32.
Once lubricant is used in the system, lubrication must be continued because the
original lubricant applied during manufacturing will be washed away.
4 MAINTENANCE
WARNING:
Not following proper procedures could cause the product to malfunction and could
lead to damage to the equipment or machine.
