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.
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 (such as the installation of a
cover or the restricting of access to the product) to prevent
potential danger caused by actuator operation.
3. Intermediate stops
For 3-position closed center, it is difficult to make a piston stop at
the required position accurately due to the compressibility of air.
Furthermore, since valves and cylinders are not guaranteed for
zero air leakage, it may not be possible to hold a stopped
position for an extended period of time. Please contact SMC if it
is necessary to hold a stopped position for an extended period
of time.
4. Effect of back pressure when using a manifold.
Use caution when valves are used on a manifold because
actuators may malfunction due to back pressure. For 3-position
exhaust center valve of single acting cylinder, take appropriate
measures to prevent the malfunction by using it with an
individual exhaust manifold.
5. 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.
6. 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.
7. Release of residual pressure
For maintenance and inspection purposes install a system for
releasing residual pressure. Especially in the case of
3-position closed center valve, ensure that the residual pressure
between the valve and the cylinder is released.
8. 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.
9. Regarding a vacuum switch valves and
vacuum release valves
If a non-vacuum valve is installed in the middle of a piping system that
contains a vacuum, the vacuum condition will not be maintained. Use
a valve designed for use under vacuum conditions.
10. Double solenoid type
When using the double solenoid type for the first time, actuators
may travel in an unexpected direction depending on the switching
position of the valve. Implement measures to prevent any danger
from occurring when operating the actuator.
11. 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.
12. 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/JSY
series, or a valve with a power-saving circuit
- Direct operated: Acontinuous duty type valve such as the VK
series or the VT series If conflicting instructions are given in the
“Specific Product Precautions” or on the “How to Order Valves”
page, give them priority.
13. Do not disassemble the product of make any
modifications, including additional
machining.
Doing so may cause human injury and/or an accident.
14. Resumption after a long period of holding time
When resuming operation after a long period of holding time,
there are cases in which, regardless of whether the product is
in an ON or OFF state, there is a delay in the initial response
time due to adhesion.
Conducting several cycles of running-in operation will solve this
problem. Please consider implementing this before resumption.
1. Precautions for 2-position double solenoid valves
If a double solenoid valve is operated with momentary
energization, it should be energized for at least 0.1 second.
However, depending on the piping conditions, the cylinder may
malfunction even when the double solenoid valve is energized
for 0.1 seconds or longer. In this case, energize the double
solenoid valve until the cylinder is exhausted completely.
2. Leakage voltage
Take note that the leakage voltage
will increase when a resistor is used
in parallel with switching element or a
C-R circuit (surge voltage
suppressor) is used for protecting a
switching device because of the
passing leakage voltage through the
C-R circuit.
The suppressor residual leakage voltage should be as 3% or less
of the rated voltage.
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.

Design / Selection
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.
4. Surge voltage intrusion
With non-polar type solenoid valves, at times of sudden
interruption of the loading power supply, such as emergency
shutdown, surge voltage intrusion may be generated from
loading equipment with a large capacity (power consumption),
and a solenoid valve in a de-energized state may switch over
(see Figure 1).
When installing a breaker circuit for the loading power supply,
consider using a solenoid valve with polarity (with polarity
protection diode), or install a surge absorption diode between
the loading equipment COM line and the output equipment
COM line (see Figure 2).
5. Operation in low temperature conditions
It is possible to operate a valve in extreme temperatures, as
low as –10°C. Take appropriate measures to avoid the
freezing of drainage, moisture, etc., in low temperatures.
6. Operation for air blowing
When using a solenoid valve for air blowing, use an external pilot
type. Use caution because the pressure drop caused by the air
blowing can have an effect on the internal pilot type valve when
internal pilot type valves and external pilot type valves are used
on the same manifold.
Additionally, when compressed air within the pressure range of
the established specifications is supplied to the external pilot type
valve’s port, and a double solenoid valve is used for air blowing,
the solenoids should be energized when air is being blown.
7. Mounting orientation
Mounting orientation is free.
8. Initial lubrication of main valve
The initial lubricant (Grease) has already been applied to the
main valve.
Please consult with SMC, as there are some standard valve
products that use fluorine grease for food processing equipment
(NSF H-1).
9. For the pilot EXH. (PE) port
If the solenoid valve and the manifold’s pilot EXH (PE) port is
restricted extremely or blocked, abnormal operation of the
solenoid valve may occur.
Mounting
1. Operation manual
Install the products and operate them only after reading the
operation manual carefully and understanding its contents.Also,
keep the manual where it can be referred to as necessary.
2. Ensure sufficient space for maintenance
activities.
When installing the products, allow access for maintenance and
inspection.
3. Tighten threads with the proper tightening
torque.
When installing the products, follow the listed torque specifications.
4. If air leakage increases or equipment does not
operated properly, stop operation.
Check mounting conditions when air and power supplies are
connected. Initial function and leakage tests should be performed
after installation.
5. Painting and coating
Warnings or specifications printed or affixed to the product
should not be erased, removed or covered up.
Please consult with SMC before applying paint to resinous parts, as
this may have an adverse effect due to the solvent in the paint.
Piping
1. Refer to the Fittings and Tubing Precautions
for handling one-touch fittings.
2. Closed center
For closed center, check the piping to prevent air leakage
from the piping between the valve and the cylinder.
3. Piping to products
When piping to a product, avoid mistakes regarding the supply
port, etc.

Wiring
1. The solenoid valve is an electrical product. For
safety, install an appropriate fuse and circuit
breaker before use.
1. Polarity
When connecting power to a solenoid valve with a DC
specification and equipped with a light or surge voltage
suppressor, check for polarity. If there is polarity, take note of
the following.
No diode to protect polarity.
If a mistake is mode regarding the polarity, damage may occur
to the diode in the valve, the switching element in a control
device or power supply equipment, etc.
With diode to protect polarity.
If polarity connection is wrong, the valve will not operate.
2. 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.
3. Check the connections.
Check if the connections are correct after completing all wiring.
Lubrication
1. Lubrication
1) The valve has been lubricated for life by the factory and does
not require any further.
2) If a lubricant is used in the system, use class 1 turbine oil (no
additives), ISO VG32. For details about lubricant
manufacturers’ brands, refer to the SMC website. Additionally,
please contact SMC for details about class 2 turbine oil (with
additives) ISO VG32. Once lubricant is utilized within the
system, since the original lubricant applied within the product
during manufacturing will be washed away, please continue to
supply lubrication to the system. Without continued lubrication,
malfunctions could occur.
If turbine oil is used, refer to the Safety Data Sheet (SDS) of
the oil.
2. Lubrication amount
If the lubrication amount is excessive, the oil may accumulate
inside the pilot valve, causing malfunction or response delay.
So, do not apply a large amount of oil. When a large amount of
oil needs to be applied, use an external pilot type to put the
supply air on the pilot valve side in the non-lube state. This
prevents the accumulation of oil inside the pilot valve.
Air Supply
1. Type of fluids
Please consult with SMC when using the product in applications
other than compressed air.
2. When there is a large amount of drainage.
Compressed air containing a large amount of drainage can
cause malfunction of pneumatic equipment. An air dryer or
water separator should be installed upstream from filters.
3. Drain flushing
If condensation in the drain bowl is not emptied on a regular
basis, the bowl will overflow and allow the condensation to enter
the compressed air lines. It causes malfunction of pneumatic
equipment. If the drain bowl is difficult to check and remove,
installation of a drain bowl with an auto drain option is
recommended.
For compressed air quality, refer to SMC’s Best Pneumatics
catalog.
4. Use clean air
Do not use compressed air that contains chemicals, synthetic
oils including organic solvents, salt or
corrosive gasses, etc., as it can cause damage or
malfunction.
1. When extremely dry air is used as the fluid,
degradation of the lubrication properties inside
the equipment may occur, resulting in reduced
reliability (or reduced service life) of the
equipment. Please consult with SMC.
2. Install an air filter.
Install an air filter upstream near the valve. Select an air filter
with a filtration size of 5 μm or smaller.
3. Take measures to ensure air quality, such as
by installing an aftercooler, air dryer, or water
separator.
Compressed air that contains a large amount of drainage can
cause the malfunction of pneumatic equipment, such as valves.
Therefore, take appropriate measures to ensure air quality, such
as by providing an aftercooler, air dryer, or water separator.
4. If an excessive amount of carbon powder is
present, install a mist separator on the
upstream side of the valve.
If excessive carbon dust is generated by the compressor, it may
adhere to the inside of a valve and cause it to malfunction.
For compressed air quality, refer to the SMC Best Pneumatics
catalog.

chemicals, sea water, water, water steam, or where there
is direct contact with any of these.
2. Products with IP65 and IP67 enclosures (based on
IEC60529) are protected against dust and water.
However, these products cannot be used in water.
3. Products compliant with IP65 and IP67 satisfy the
product specifications when mounted properly. Be sure
to read the precautions for each product.
4. Do not use in an environment where flammable gas or
explosive gas exists. Usage may cause a fire or
explosion. The products do not have an explosion proof
construction.
5. Do not use in a place subject to heavy vibration and/or
shock.
6. The valve should not be exposed to prolonged sunlight.
Use a protective cover. Note that the valve is not for
outdoor use.
7. Remove any sources of excessive heat.
8. If it is used in an environment where there is possible
contact with oil, weld spatter, etc., exercise preventive
measures.
9. When the solenoid valve is mounted in a control panel or
it’s energized for a long period of time, make sure the
ambient temperature is within the specifications of the
valve.
1. Temperature of ambient environment
Use the valve within the range of the ambient temperature
specification of each valve. In addition, pay attention when
using the valve in environments where the temperature
changes drastically.
2. Humidity of ambient environment
- When using the valve in environments with low humidity, take
measures to prevent static.
- If the humidity rises, take measures to prevent the adhesion of
water droplets on the valve.
Maintenance
1. Perform maintenance and inspection
according to the procedures indicated in the
operation manual.
If handled improperly, human injury and/or malfunction or
damage of machinery and equipment may occur.
2. Removal of equipment, and supply/exhaust of
compressed air
Before components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply air and electric power,
and exhaust all air pressure from the system using the residual
pressure release function.
For the 3-position closed center, exhaust the residual pressure
between the valve and thecylinder. When the equipment is
operated after remounting or replacement, first confirm that
measures are in place to prevent the lurching of actuators, etc.
Then, confirm that the equipment is operating normally. In
particular, when a 2-position double solenoid valve is used,
releasing residual pressure rapidly may cause the spool valve
to malfunction, depending on the piping conditions, or the
connected actuator to operate.
3. Low-frequency operation
Valves should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air supply.)
4. Manual override
When a manual override is operated, connected equipment will
be actuated.
Operate only after safety is confirmed.
5. If the volume of air leakage increases or the
valve does not operate normally, do not use the
valve.
Perform periodic maintenance on the valve to
confirm the operating condition and check for
any air leakage.
1. Drain flushing
Remove drainage from the air filters regularly.
2. Lubrication
In the case of rubber seals, once lubrication has been started, it
must be continued.
Use class 1 turbine oil (with no additives), VG32. If other
lubricant oil is used, it may cause a malfunction. Please contact
SMC for information on the suggested class 2 turbine oil (with
additives), VG32.
3. Manual override operation
When switching a double solenoid valve via the manual
override operation, instantaneous operation may cause the
malfunction of the cylinder. It is recommended that the manual
override be held until the cylinder reaches the stroke end
position.
