delivered,whichever is first.
∗
2)
Also, the product may have speci f i ed durability, running distance or replacement parts. Please
consult your nearest sales branch.
2. For any failure or da mage reported within the warra nty period which is clearly our r es ponsibility,

pad or failure due to the deterioration of rubber material are not covered by the limited
warranty.
Compliance Requireme nt s
1.
The use of SMC products with production equipment for the manufacture of weapons of mass
destruction(WMD) or any other weapon is strictl y prohibited.
2. The exports of SMC products or technology from one country to another are governed by the
relevant
security laws and regulation of the countries involved in the transaction. Prior to the
shipment of a SMC product to another country, assure that all local rules governing that export
are known and f
ollowed.
Caution
SMC products are not intended for use as instruments for legal metrology.
Measurement instruments that SMC manufactures or sells have not been qualified by type approval tests
relevant to the metrology (measurement) laws of each country.
Therefore, SMC products cannot be used for business or certification ordained by the metrology
(measurement) laws of each country.

Design / Selection
1. Confirm the specifications
Products represented in this instruction manual 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 the specifications.) Please contact
SMC when using a fluid other than compressed air (including
vacuum). We do not guarantee against any damage if the
product is used outside of the specification range.
2. Actuator drive
When an actuator, such as a cylinder, is to be driven using a
valve, take appropriate measures (cover installation or
approach prohibition) to prevent potential danger caused by
actuator operation.
3. Effect of back pressure when using a manifold.
Use caution when valves are used on a manifold, because
an actuator may malfunction due to
back-pressure.
4. Holding pressure (including vacuum).
Since the valve are subject to air leakage, they cannot be
used for applications such as holding pressure (including
vacuum) in a pressure vessel.
5. Not suitable for use as an emergency shut-off
valve, etc.
The valves listed in this instruction manual are not designed
for safety applications such as an emergency shutoff valve. If
the valves are used for the mentioned applications, additional
safety measures should be adopted.
6. Release of residual pressure
For maintenance purposes install a system for releasing
residual pressure.
7. Operation in a vacuum condition
When a valve is used for switching a vacuum, take measures
to install a suction filter or similar to prevent external dust
or other foreign matter from entering inside the valve. In
addition, at the time of vacuum adsorption, be sure to supply
a constant supply of vacuum. Failure to do so may result in
foreign matter sticking to the adsorption pad or air leakage,
causing the workpiece to drop.
8. Regarding a vacuum switch valve
For maintenance purposes install a system for releasing
residual pressure.
9. Ventilation
Provide ventilation when using a valve in a confined area,
such as in a closed control panel. For example, install a
ventilation opening, etc. in order to prevent pressure from
increasing inside of the confined area and to release the heat
generated by the valve.
10. Extended periods of continuous energization.
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 operation the energized period per day is
longer than the de-energized period, we advise using a valve
with specifications listed below.
• Pilot operated: A 0.4 W or lower valve, such as the SY
series, or a valve with a power-saving circuit
11. Do not disassemble the product of make any
modifications, including addit ional mach ining.
It may cause human injury and/or an accident.
1. Leakage voltage
Take note that the leakage voltage will increase when a
resistor is used in parallel with a switching element or when a
C-R circuit (surge voltage suppressor) is used for protecting a
switching device because of the leakage voltage passing
through the C-R circuit. The suppressor residual leakage
voltage should be as follows.
DC coil
3% or less of the rated voltage
AC coil 8% or less of the rated voltage
2. Solenoid valve drive for AC with a solid state
output (SSR, TRIAC output, etc.)
1) Current leakage
When using a snubber circuit (C-R element) for surge
protection of the output, a very small amount of
electrical current will continue to flow even during the
OFF state. This results in the valve not returning. In a
situation where the tolerance is exceeded, as in the
above case, take measures to install a bleeder
resistor.
2) Minimum allowable load amount (Min. load current)
When the consumption current of a valve is less than
the output’s minimum allowable load volume or the
margin is small, the output may not switch normally.
Please contact SMC.
3) Solenoid valve with full wave rectifier circuit
When the solenoid valve built-in full wave rectif i er
circuit with AC specifications is used, a return failure of
the solenoid valve may occur depending on the kind of
triac output circuit. Carefully check this point when
selecting a SSR or sequencer. For details, contact the
SSR or sequencer manufacturer.
3. Surge voltage suppressor
1) The surge voltage suppressor built into the valve is
intended to protect the output contacts so that the surge
generated inside valve does not adversely affect the output
contacts. Therefore, if an overvoltage or overcurrent is
received from an external peripheral device, the surge
voltage protection element inside the valve is overloaded,
causing the element to break. In the worst case, the
breakage causes the electric circuit to enter short-circuit
status. If energizing continues while in this state, a large
current flows. This may cause secondary damage to the
output circuit, external peripheral device, or valve, and may
also cause a fire. So, take appropriate protective measures,
such as the installation of an overcurrent protection circuit
in the power supply or a drive circuit to maintain a sufficient
level of safety.
2) If a surge protection circuit contains nonstandard diodes,
such as Zener diodes or varistor, a residual voltage that is
in proportion to the protective circuit and the rated voltage
will remain. Therefore, take into consideration the surge
voltage protection of the controller. In the case of diodes,
the residual voltage is approximately 1V.
