Note 1) With the low vacuum specification, the operating pressure range is 1.33 x
102Pa to the maximum operating pressure.
Note 2) Use dry air to prevent condensation when operating at low temperatures.
Note 3) 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. (Values quoted are for a new valve).
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. (Values
quoted are for a new valve).

3 Installation
3.1 Installation Warning
•Do not install the product unless the safety instructions have been read
and understood.
3.2 Environment Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•Do not use in an explosive atmosphere.
•Do not expose to direct sunlight. Use a suitable protective cover.
•Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
3 Installation - continued
3.3 Piping Caution
•Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread exposed
on the end of the pipe/fitting.
•Tighten M3screws 1/4turn past hand tightness, andM5 screws by 1/6
turn past hand tightness (1/4 turn for miniature fittings) and to the
specified tightening torque as per below table.

3.4 Lubrication Caution
•SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•If a lubricant is used in the system, refer to catalogue for details.
3.5 Air supply Warning
•Use clean air. If the compressed air supply includes chemicals,
synthetic materials (including organic solvents), salinity, corrosive gas
etc., it can lead to damage or malfunction.
Caution
•Install an air filter upstream of the valve. Select an air filter with a
filtration size of 5 μm or smaller.
3.6 Mounting
Caution
•Ensure gaskets are in good condition, not deformed and are dust and
debris free.
•When mounting valves ensure gaskets are present, aligned and
securely in place. After tightening by hand, tighten an additional 1/4
rotation for M3 and 1/6 rotation for M5. Tighten the screws to torque
levels as per figure below.
•Refer to catalogue for additional information.

3.7 Electrical circuits Caution
Surge suppression should be specified by using the appropriate part
number. If a valve type without suppression (Type ‘G’) is used,
suppression must be provided by the host controller as close as possible
to the valve.

Table 4.
Note) There is no polarity for Grommet type or Plug lead type.
3.8 Residual voltage of the surge voltage suppressor
Caution
•The suppressor arrests the back EMF voltage from the coil to a level
in proportion to the rated voltage.
•Ensure the transient voltage is within the specification of the host
controller.
•Contact SMC for the varistor residual voltage.
•In the case of a diode, the residual voltage is approximately 1 V.
•Valve response time is dependent on surge suppression method
selected.
3.9 Countermeasure for surge voltage
Caution
•At times of sudden interruption of the power supply, the energy stored
in a large inductive device may cause non-polar type valves in a de-
energized state to switch.
•When installing a breaker circuit to isolate the power, consider a valve
with polarity (with polarity protection diode), or install a surge
absorption diode across the output of the breaker.
3.10 Extended periods of continuous energization
Warning
If a valve will be continuously energized for an extended period of time,
the temperature of the valve will increase due to the heat generated by
the coil assembly. This will likely adversely affect the performance of the
valve and any nearby peripheral equipment. Therefore, if the valve is to
be energized for periods of longer than 30 minutes at a time or if during
the hours of operationthe energized period per day is longer than thede-
energized period, we advise using valves with power saving circuit (type
E or F).
3.11 Effect of back pressure when using a manifold
Warning
Use caution when valves are used on a manifold because an actuator
may malfunction due to back-pressure.

6 Maintenance - continued
•Maintenance of pneumatic systems should be performed only by
qualified personnel.
•Before performing maintenance, turn off the power supply and be sure
to cut off the supply pressure. Confirm that the air is released to
atmosphere.
•After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
•If any electricalconnections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.
6.2 Replacement parts
Refer to catalogue for replacement parts.
6.3 Addition and removal of manifold stations
Refer to catalogue for additional information.
7 Limitations of Use
7.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
Warning
7.2 Return of the valve to the de-energised position
When electricity is cut, the valve returns to the de-energised position by
spring force.
7.3 Holding of pressure
Since valves are subject to air leakage, they cannot be used for
applications such as holding pressure (including vacuum) in a system.
7.4 Cannot be used as an emergency shut-off valve
This product is not designed for safety applications such as an
emergency shut-off valve. If the valves are used in this type of system,
other reliable safety assurance measures should be adopted.
Caution
7.5 Leakage voltage
Ensure that any leakage voltagecaused by the leakage current when the
switching element is OFF causes ≤ 2% of rated voltage across the valve.
7.6 Low temperature operation
Unless otherwise indicated in the specifications for each valve, operation
is possible to -10˚C, but appropriate measures should be taken to avoid
solidification or freezing of drainage and moisture, etc.
7.7 Vacuum release application
•Use 3 (R) port for vacuum pressure and 1 (P) port for vacuum release
pressure.
•Set the pressure so that the pressure difference between the 3(R) and
1(P) ports does not exceed the maximum operating pressure of the
valve.
•When the 3(R) port is used for the vacuum release (atmospheric
pressure to positive pressure) and the 1(P)port is used forthe vacuum,
use the normally open (N.O.) specifications.
