Kerosene, Fuel oil class 1 (fuel oil A), Silicone oil, Machine oil,
Compressor oil, Gas oil, Hydraulic fluid, Turbine oil
Improved durability (nearly twice
High speed response
the life of the previous VX series)
The internal wear of moving parts has been reduced
through the use of a unique magnetic material.
Service life, durability and corrosion resistance have
been increased.
(nearly twice the previous VX series)
(Class 3)
High flow rate: Cv factor 0.16 to 2.1
Smaller size: Single valve – 15% reduction in volume (Class 3)
Manifold length – Reduced by 18% (Class 3: 5 stations) (SMC comparison)
Clip type
Internal surge voltage suppressor
(Class B coil)
Quick change coils
Internal rectifier
circuit (AC)
Clip design makes coil
replacement easy
• AC/DC switchover is possible
by simply changing the coil
• Reduced noise
Incombustible molded coil material
Note) For Class B coil
Conforms to UL94 V-0
Coil size and weight reduced
New compact coil reduces the overall
size & weight of the valve
Volume – 15%
Weight – 20%

Pressure Terminology
1. Maximum operating pressure differential
This indicates the maximum pressure differential (upstream
and downstream pressure differential) 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 system pressure
This indicates the limit of pressure that can be applied inside the

Electrical Terminology
1. Surge voltage
A high voltage which is momentarily generated in the shut-off unit by
shutting off the power.
Other
Q : Flow rate (l/min)
∆P: Pressure differential (P1– P2)
P1 : Upstream pressure (MPa)

1. Materials
FKM: Fluoro rubber – Trade names: Viton®, Dai-el, etc.
2. Symbols
In the JIS symbol (
) IN and OUT are in a blocked condition
( ), but actually in the case of reverse pressure (OUT>IN), there
is a limit to the blocking capability. (
) is used to indicate that
blocking of reverse pressure is not possible.
Note) In case of a viscous fluid, there may be a difference between the flow
rate found with the above formulas and the actual flow rate, depending
on the viscosity.

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 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.

Precautions on Design
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
Contact 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 protection.
5. Maintenance space
The installation should allow sufficient space for maintenance
activities (removal of valve, etc.).
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. Fluids
Before using a fluid, confirm whether or not it is compatible by
referring to the fluids listed in this catalog. Use fluids with a viscosity of no more than 50mm²/s (50cSt).
Consult SMC regarding any further questions.
3. Fluid temperature
Operate within the fluid temperature range. The temperature
range varies depending on the seal material, coil insulation and
type of power supply, etc.
4. 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 core, 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.
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.

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.
Further, when pipe tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the pipe/fitting.
Winding
direction
Use tape and 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.
5. Avoid sources of vibration, or set 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.
4. Always fasten threads with the proper
tightening torque.
When screwing fittings into valves, fasten with the proper tightening torques as shown below.

Wiring
Conduit terminal
Caution
1. As a rule, use electrical wire of 0.5 to
1.25mm².
Further, 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 using class H coils where the electrical
circuit system does not allow solenoid surge,
install a surge absorber, etc., in parallel with
the solenoid.
