Explanation of Terminology
Pressure Terminology
1. Maximum operating pressure differential
This indicates the maximum pressure differential (the difference between the upstream and downstream pressure) which
can be allowed for operation with the valve closed or open.
When the downstream pressure is 0MPa, this becomes the
maximum operating pressure.
2. Maximum operating pressure
This indicates the upper limit of pressure that can be applied
inside the pipelines (line pressure).
(The pressure differential of the solenoid valve unit must be no
more than the maximum operating pressure differential.)
3. Proof pressure
The pressure which must be withstood without deterioration in
performance when the valve returns to the operating pressure
range (the value under the specified conditions).
Electrical Terminology
1. Surge voltage
A high voltage which is momentarily generated in the shut-off unit
by shutting off the power.

Safety Instructions
These safety instructions are intended to prevent a hazardous situation and/or
equipment damage. These instructions indicate the level of potential hazard by a
label of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe
ISO 4414 Note 1) and other safety practices.
Caution :
Operator error could result in injury or equipment damage.
Warning :
Operator error could result in serious injury or loss of life.
Danger :
In extreme conditions, there is a possible result of serious injury or loss of life.
Note 1) ISO 4414 : Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control
systems
Warning
1. The compatibility of equipment is the responsibility of the person who designs
the system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility for the
specific system must be based on specifications or after analysis and/or tests to meet your specific
requirements. Be particularly careful in determining the compatibility of the fluid to be used.
2. Only trained personnel should operate machinery and equipment.
The fluid can be dangerous if handled incorrectly. Assembly, handling or repair of systems should be
performed by trained and experienced operators.
3. Do not service machinery/equipment or attempt to remove components until
safety is confirmed.
1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe
locked-out control positions and measures to prevent danger from the fluid.
2. When equipment is to be removed, confirm the safety process as mentioned above, release fluid
pressure and be certain there is no danger from fluid leakage or fluid remaining in the system.
3. Restart machinery carefully, confirming that safety measures are being implemented.
4. Contact SMC if the product is to be used in any of the following conditions:
1. Conditions and environments beyond the given specifications, or if product is used outdoors.
2. With fluids whose application causes concern due to the type of fluid or additives, etc.
3. An application which has the possibility of having negative effects on people, property, or animals,
requiring special safety analysis.

2 Port Solenoid Valve for Fluid Control Precautions 1
Be sure to read before handling.
Design
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
Consult SMC if valves will be continuously energized for extended periods of time.
3. Liquid seals
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.
Warning
1. Confirm the specifications.
Give careful consideration to operating conditions such as the
application, fluid and environment, and use within the operating ranges specified in this catalog.
2. Fluid temperature
Operate within the prescribed fluid temperature range. The
temperature range changes depending on the seal material,
coil insulation and the type of power supply, etc.
3. Fluid quality
The use of 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. As a general rule, use 80
to 100 mesh.
When used to supply water to boilers, substances such as calcium and magnesium which generate hard scale and sludge
are included. Since this scale and sludge can cause valve malfunction, install water softening equipment, and a filter (strainer) directly upstream from the valve to remove these substances.
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 and C-R element, etc., creating a
danger that the valve may not shut OFF.

2. Low temperature operation
1. The valve can be used at ambient temperatures as low as
–20°C, but take measures to prevent freezing or solidification of impurities, etc.
2. When used in cold areas, adopt freeze prevention measures
such as draining the water from pipelines. If warmed with a
heater, etc., avoid the coil unit. Also, implement warming or
other freeze prevention measures for the body.

2 Port Solenoid Valve for Fluid Control Precautions 2
Be sure to read before handling.
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
When connecting pipes and fittings, etc., be sure that chips from
the pipe threads and sealing material do not get inside the
valve.
Furthermore, when pipe tape is used, leave 1.5 to 2 thread
ridges exposed at the end of the threads.
Winding
direction
Use tape and heaters, etc., for freeze prevention on the piping
and body only. They can cause burn out of the coil.
4. Secure with brackets, except in the case of
steel piping and copper fittings.
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
Mount the product after reading the manual carefully and understanding its contents. Also keep the manual where it can be referred to as necessary.
7. Painting and coating
Warnings or specifications printed or pasted on the product
should not be erased, removed or covered up.

3. Avoid connection of ground lines to piping,
as this may cause electric corrosion of the
system.

2 Port Solenoid Valve for Fluid Control Precautions 3
Be sure to read before handling.
Wiring
Operating Environment
1. As a rule, use electrical wire with a cross
sectional area of 0.5 to 1.25mm² for wiring.
Furthermore, do not allow excessive force to
be applied to the lines.
2. Use electrical circuits which do not generate
chattering in their contacts.
3. Use voltage which is within ±10% of the rated
voltage. 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.
4. When surge from the solenoid affects the
electrical circuitry, install a surge absorber,
etc., in parallel with the solenoid.
1. Do not use valves in atmospheres of corrosive
gases, chemicals, salt water, water, or where
there is direct contact with any of these.
2. Do not use in explosive atmospheres.
3. Do not use in locations subject to vibration or
impact.
4. Do not use in locations where radiated heat
will be received from nearby heat sources.
5. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc.
