Note 1) Use dry air and prevent condensation at low temperatures.
Note 2) Vibration resistance: No malfunction resulted in 45 to 2000 Hz, a one-sweep test performed in
the axial and right angle directions of the main valve and armature for both
energized and de-energized states.
Impact resistance: No malfunction resulted in an impact test using a drop impact tester. The
test was performed one time each in the axial and right angle directions of
the main valve and armature, for both energized and de-energized states.
With the 0.1 W specification, the vibration and impact resistance is 10/50 m/s2 or less.
Note 3) With the low vacuum specification, the operating pressure range is 1.33 × 102 Pa to the maximum
operating pressure.

3 Port Solenoid Valve/Common Precautions 1
Be sure to read before handling.
Selection
Design
When an actuator, such as a cylinder, is to be driven using a
valve, take appropriate measures to prevent potential danger
caused by actuator operation.
2. Effect of back pressure when using a valve
Use caution when valves are manifolded because actuator
malfunction due to back-pressure may occur.
3. Holding pressure (including vacuum)
Since valves are subject to air leakage, they cannot be used
for applications such as holding pressure (including vacuum)
in a pressure vessel.
4. The valve cannot be used as an emergency
shutoff valve, etc.
The valves presented in this catalog are not designed for safety applications such as an emergency shutoff valve. If the
valves are used in this type of system, other reliable safety assurance measures should also be adopted.
5. Maintenance space
The installation should allow sufficient space for maintenance
activities (removal of valve, etc.).
6. Release of residual pressure
Provide a residual pressure release function for maintenance
purposes.
7. Vacuum applications
When a valve is used for vacuum switching, take appropriate
measures against the suction of external dust or other contaminants through vacuum pads and exhaust ports.
8. Ventilation
When a valve is used inside a sealed control panel, etc., provide ventilation to prevent a pressure increase caused by exhausted air inside the control panel or temperature rise caused
by the heat generated by the valve.
Warning
1. Confirm the specification.
The products presented in this catalog are designed only for
use in compressed air systems (including vacuum). Do not operate at pressures or temperatures, etc., beyond the range of
specifications, as this can cause damage or malfunction. (Refer to specifications.)
Contact SMC when using a fluid other than compressed air
(including vacuum).
2. Extended periods of continuous energization
• Continuous energization of the valve for extended periods of
time may have an adverse effect on the solenoid valve performance and the peripheral equipment due to temperature
rises caused by the heat generation of the coil. Please consult SMC if valves will be continuously energized for extended periods of time or the energized period per day will be
longer than the de-energized period. It is also possible to
shorten the energization period by using valves of the N.O.
(normally open) type.
• When solenoid valves are mounted in a control panel, employ measures to radiate excess heat, so that temperatures
remain within the valve specification range. Use special caution when three or more stations sequentially aligned on the
manifold are continuously energized since this will cause a
drastic temperature rise.

Warning
1. Actuator drive
2. Surge voltage suppressor
If a surge protection circuit contains diodes other than ordinary
types of diodes such as Zener diodes or ZNRs, a residual voltage that is in proportion to the protective elements and the
rated voltage will remain. Therefore, give consideration to
surge voltage protection of the controller.
3. Low temperature operation
Valve use is possible to temperature extremes to –10°C. Take
appropriate measures to avoid freezing of drainage, moisture
etc.
4. Mounting orientation
Refer to the specifications.

Lubrication
Caution
1. If air leakage increases or equipment does
not operate properly, stop operation.
Check moutning conditions when air and power supplies are
connected. Initial function and leakage tests should be performed after installation.
1. Lubrication
1) The valve has been lubricated for life at the manufacturer,
and does not require further lubrication in service.
2) If a lubricant is applied in the system, use turbine oil class 1
(no additives), ISO VG32.
2. Instruction manual
Mount and operate the product after reading the manual carefully and understanding its contents.
Also keep the manual where it can be referred to as necessary.
3. Painting and coating
Warnings or specifications printed or pasted on the product
should not be erased, removed or covered up.
Consult SMC if paint is to be applied to resinous parts, as this
may have an adverse effect due to the paint solvent.
Air Supply
Warning
1. Use clean air.
Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases,
etc., as this can cause damage or malfunction.
Caution
Piping
1. Install air filters.
Install air filters close to valves at their upstream side. A filtration degree of 5 µm or less should be selected.
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
2. Screwing in fittings
When screwing fittings into valves, tighten as follows.
1) M3, M5
(1) When installing SMC fittings, etc., follow the procedures
below.
After tightening by hand, tighten an additional 1/4 rotation
for M3 and 1/6 rotation for M5 with a tool. However, when
using a miniature fitting, tighten an additional 1/4 rotation
with a tool after tightening by hand. Also, when there are 2
gaskets such as in case of a universal elbow or universal
tee, tighten an additional 1/2 rotation.
Note) If overtightened, threaded part may be broken or gasket
deformed. If tightened insufficiently, thread part may be
loosened. In either case, air leakage could occur.
(2) When using a fitting brand other than SMC, follow the instruction by the manufacturer of the fittings.
2. Install an air dryer, after-cooler or water separator, etc.
Air that includes excessive drainage may cause malfunction of
valves and other pneumatic equipment. To prevent this, install
an air dryer, after-cooler or water separator, etc.
3. If excessive carbon dust is generated, eliminate it by installing mist separators at the upstream side of valves.
If excessive carbon dust is generated by the compressor, it
may adhere to the inside of valves and cause malfunction.
Refer to SMC’s “Best Pneumatics Vol. 4” catalog for compressed
air quality.
3. Connection of piping to products
When connecting piping to a product, refer to its instruction
manual to avoid mistakes regarding the supply port, etc.
Wiring
Caution
1. Applied voltage
When electric power is connected to a solenoid valve, be
careful to apply the proper voltage. Improper voltage may
cause malfunction or coil damage.
2. Confirm the connections.
After completing the wiring, confirm that the connections are
correct.

2. Do not use in an explosive atmosphere.
3. Do not use in locations subject to vibration
or impact. Confirm the specifications in the
main section of the catalog.
4. Use a protective cover, etc., to shield valves
from direct sunlight.
5. Shield valves from radiated heat generated
by nearby heat sources.
6. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc.
7. When solenoid valves are mounted in a control panel or are energized for extended periods of time, employ measures to radiate excess heat, so that temperatures remain within the valve specification range.
Warning
1. Perform maintenance procedures as shown
in the instruction manual.
If handled improperly, malfunction or damage of machinery or
equipment may occur.
2. Removal of equipment maintenance and
supply/exhaust of compressed air
When equipment is serviced, first confirm that measures are in
place to prevent dropping of work pieces and run-away of
equipment, etc. Then cut the supply pressure and power, and
exhaust all compressed air from the system using its residual
pressure release function.
When the equipment is to be started again after remounting or
replacement, first confirm that measures are in place to prevent lurching of actuators, etc., and then confirm that the
equipment is operating normally.
3. Low frequency operation
Valves should be switched at least once every 30 days to prevent malfunction. (Use caution regarding the air supply.)
Caution
1. Drain flushing
Remove drainage from air filters regularly.
2. Lubrication
Once lubrication has been started, it must be continued.
And use turbine oil Class 1 (no additives), VG32. If other lubricant oil is used, it may cause malfunction. Contact us for suggested turbine oil Class 2(with additive), VG32.

to the required length.
2. Base mounted with clips
1 Hook a flat head watchmakers screwdriver into the hole of
the metal bracket and pull it approximately 1 mm in the direction indicated by the arrow. 2 Insert the solenoid valve from
above. After confirming that the bottom surface of the solenoid valve contacts the top surface of the manifold, detach the
flat head screwdriver from the mounting bracket while holding
the solenoid valve body.
(Before mounting, confirm the installation of the interface gasket on the solenoid valve body.)
2) Insert the tubing and push it all the way to the barb end. If the
tubing is not installed securely to the end, problems such as
leakage or disconnection of the tubing can occur.
3) When the tubing is inserted into the barb fitting, push it in the
direction of the tubing axis to prevent excessive lateral loads
being applied to the barb fitting.
The built-in leaf spring returns the mounting bracket to its
original position.
(Then confirm that the end of the mounting bracket is aligned
