Note 1) When used under conditions which may cause condensation on the exterior of the product,
select Grommet / Molded.
Note 2) When used with deionized water, select “L” (Stainless steel, FKM) for the material type.
Note 3) Since the AC coil specification includes a rectifier element, there is no difference in power consumption between inrush and holding.
In the case of 110/220 VAC, the VDW10 is 3 W and the VDW20/30 is 3.5 W.
Note 4) Vibration resistance ····· No malfunction when tested with one sweep of 5 to 200 Hz in the axial
direction and at a right angle to the armature, in both energized and
deenergized states.
Impact resistance ········ No malfunction when tested with a drop tester in the axial direction and
at a right angle to the armature, one time each in energized and
deenergized states.
Note 5) Since electrical connections are exposed, there is no water resistance.

Specific Product Precautions 1
Be sure to read this before handling.
Refer to front matters 42 and 43 for Safety Instructions, and pages 17 to 19 for 2 Port
Solenoid Valves for Fluid Control Precautions.
Design
Warning
1. 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.
2. Extended periods of continuous energization
Please consult with SMC when using with energization for
long periods of time.
3. Liquid rings
In cases with a flowing liquid, provide a by-pass valve in the
system to prevent the liquid from entering the liquid seal
circuit.
4. This solenoid valve cannot be used for explosion
proof applications.
5. Maintenance space
The installation should allow sufficient space for maintenance
activities (removal of valve, etc.).
Selection
Warning
1. Confirm the specifications.
Give careful consideration to the operating conditions such as
the application, fluid and environment, and use within the operating ranges specified in this catalog.
2. Fluid temperature
Please use within the operating fluid temperature range.
3. 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 80 to 100 is a guideline for the filter.
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
1. Leakage voltage
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.

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.

Specific Product Precautions 2
Be sure to read this before handling.
Refer to front matters 42 and 43 for Safety Instructions, and pages 17 to 19 for 2 Port
Solenoid Valves for Fluid Control Precautions.
Mounting
Warning
1. If air leakage increases or equipment does not operate properly, stop operation.
After mounting is completed, confirm that it has been done
correctly by performing a suitable function test.
2. Do not apply external force to the coil section.
When tightening is performed, apply a wrench or other tool to
the outside of the piping connection parts.
3. Do not warm the coil assembly with a heat insulator,
etc.
Piping
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. Wrapping of pipe tape
Winding
direction
Use tape, heaters, etc., for freeze prevention on the piping and
body only. They can cause the coil to burn out.
4. Secure with brackets, except in the case of steel
piping and copper fittings.
po
se
pr
5. Avoid sources of vibration, or adjust the arm from
the body to the minimum length so that resonance
will not occur.
6. Instruction manual
The product should be mounted and operated after the instruction manual is thoroughly read and its contents are understood. Keep the instruction manual where it can be referred to
as needed.

Wiring
Operating Environment
Caution
Warning
1. As a rule, use electrical wire with a cross sectional
area of 0.5 to 1.25 mm2 for wiring.
Furthermore, do not allow excessive force to be applied to the
lines.
1. Do not use the valves in an atmosphere having corrosive gases, chemicals, salt water, water, steam, or
where there is direct contact with any of these.
2. Do not use in explosive atmospheres.
2. Use electrical circuits which do not generate chattering in their contacts.
3. Do not use in locations subject to vibration or impact.
3. Use voltage which is within ±10% of the rated voltage.
4. Do not use in locations where radiated heat will be
received from nearby heat sources.
In cases with a DC power supply where importance is placed
on responsiveness, stay within ±5% of the rated value. The
voltage drop is the value in the lead wire section connecting
the coil.
5. Employ suitable protective measures in locations
where there is contact with water droplets, oil or
welding spatter, etc.
