Specific Product Precautions 1
Be sure to read before handling. Refer to back cover for Safety Instructions, “Handling
Precautions for SMC Products” (M-E03-3) for Fluids Control 2 Port Valves Precautions,
and Series VDW in Best Pneumatics No. 7 for Specific Product Precautions.
Selection

Warning
Warning
1. Fluid quality
In the case of water
The use of a fluid which contains foreign matter can cause
problems such as malfunction and seal failure by promoting
wear of the valve seat and armature, and by sticking to the
sliding parts of the armature, etc. Install a suitable filter
(strainer) immediately upstream from the valve. In general, a
mesh of about 50 to 100 is a guideline for the filter.
When using ordinary tap water, scaling and sludge from
substances in hard water such as calcium and magnesium
can cause solenoid valves to malfunction. It is therefore
necessary to install a water softener to remove such
substances and a filter (strainer) immediately before the
solenoid valve.
In the case of air
Please use ordinary compressed air where a filter of 40 µm or
less is provided on the inlet side piping. (Except dry air)
Caution
Particularly when using a resistor in parallel with a switching
element and using a C-R element (surge voltage suppressor)
to protect the switching element, take note that leakage current will flow through the resistor, C-R element, etc., creating
a possible danger that the valve may not turn off.

Piping
Warning
1. During use, deterioration of the tubing or damage
to the fittings could cause tubes to come loose
from their fittings and thrash about.
To prevent uncontrolled tube movement, install protective
covers or fasten tubes securely in place.
Caution
2. Connection of piping to products
1. Leakage voltage
C
1. When the valve is secured using an insert nut (part
number suffix “-N”), handle with care during
installation because the application of excessive
stress to the body could damage it (appropriate
tightening torque: 0.8 to 1.0 N·m).
• When connecting piping to a product, refer to its instruction
manual to avoid mistakes regarding the supply port, etc.
• Do not apply external force to the coil when holding it to connect piping, as the tube may deform.
• When attaching fittings to a solenoid valve, do not use fittings that do not conform to the quick fastener standard.
• Handle with care when attaching fittings because the application of excessive stress to the quick fastener portion could
damage the body.
R
Valve
Recommended Piping Conditions
Leakage current
1) Take steps to ensure that there are no problems such as
abnormal voltage drops or insufficient capacity associated
with the signal power supply used to drive the solenoid
valve.
2) Make sure the leakage current flowing through the solenoid
valve when power is not being supplied is 0.1 mA or less. If
there the leakage current is larger than this, take
appropriate measures such as connecting a bleeder
resister (models with power-saving circuit).
3) An attenuation function is provided to reduce voltage
surges produced by the solenoid valve. However, the
controller should be equipped with protection against
voltage surges as some residual surge voltage may still
reach external components.
DC coil
2% or less of rated voltage
1. When connecting tubes
using One-touch fittings,
provide some spare tube
length as shown in Fig. 1,
recommended piping configuration.
Also, do not apply external
force to the fittings when binding tubes with bands, etc. (see
Fig. 2.)

2. Low temperature operation
1) The valves can be used up to an ambient temperature of
–10°C, however take measures to prevent solidification of
impurities or freezing, etc.
2) When using valves for water application in cold climates,
first stop the water supply/discharge of the pump, etc., and
then take measures to prevent freezing such as draining
water in pipe. When heating by steam, be careful not to expose the coil portion to steam. Also, please take measures
to prevent freezing such as heating the body.

Caution
Caution
1. Solenoid valves with power-saving circuits (coil
part number “-5GE”) have polarity, so follow the
wiring diagram below when making connections.
Standard coils have no polarity.
The maximum operating pressure differential differs depending
on the flow direction of the fluid. If the pressure differential at
each port exceeds the values in the table below, valve leakage
may occur.

The solenoid valve will not switch properly if the polarity is reversed.

Maintenance
Warning
1. Do not disassemble solenoid valves.
Disassembling a solenoid valve will void its warranty.
2. Low frequency operation
Switch valves at least once every 30 days to prevent
malfunction. Also, in order to use it under the optimum state,
conduct a regular inspection once a half year.
Caution
1. Store indoors in a location away from direct sunlight and where the following conditions are maintained.
• Temperature: –10 to 50°C
• Relative humidity: 20% to 85%RH (No condensation)
• Liquid rings may not be used.
2. Storage
When not using for a long time (more than approx. one
month) after use with liquid, thoroughly remove all moisture to
prevent rust and deterioration of rubber materials, etc.
