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 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 series)
(Class 3)
High flow rate: Nl/min 187 to 2061
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
pipelines. (line pressure)
(The pressure differential of the solenoid valve unit must be no
more than the maximum operating pressure differential.)
3. Withstand pressure
IN
N.C.
The pressure which must be withstood without a drop in
performance after returning to the operating pressure range.
(value under the prescribed conditions)

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.

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.
Electrical Connections
In the case of the conduit terminal, make connections according to
the marks shown below.

Be sure to read before handling.
Operating Environment
Warning
1. Do not use valves in atmospheres of
corrosive gases, chemicals, salt water, water
or steam, or where there is direct contact
with same.
2. Do not use in an explosive atmosphere.
3. Do not use in locations subject to vibration or
impact.
4. Do not use in a location where radiated heat
will be received from a heat source in the
vicinity.
5. Employ suitable protective measures in
locations where there is contact with water
droplets, oil or welding spatter, etc.
Maintenance
Warning
1. Perform maintenance in accordance with the
procedures in the instruction manual.

Caution
1. Filters and strainers
1. Be careful regarding clogging of filters and strainers.
2. Replace filters after one year of use, or earlier if the amount
of pressure drop reaches 0.1MPa.
3. Clean strainers when the amount of pressure drop reaches
0.1MPa.
