Series VCW
Improved durability
(SMC comparison: Twice the life of 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.
Large flow rate:
Nl/min 157 to 2061
Smaller size: Single valve –15% reduction in volume (Class 2)
Manifold length – Reduced by 18%
(Class 3 : 7 stations) (SMC comparison)
Internal surge voltage suppressor
Clip type
Quick change coils
Clip design makes coil
replacement easy
Internal rectifier circuit (AC)
• AC/DC switchover is possible by simply
changing the coil
• Reduced noise
Incombustibility UL94
Conforms to V-0
Miniaturized coil
Size and weight reduced
New compact coil reduces the overall
size & weight of the valve
Volume –15% SMC comparison
Weight –20% (Class 2)

1. Maximum operating pressure differential
This indicates the maximum pressure differential (upstream
pressure 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 less
than the maximum operating pressure differential.)
3. Withstand pressure
The pressure which must be withstood without a drop in
performance after returning to the operating pressure range.

How to find the flow rate for water
• Formula based on Cv factor
Q=14.2⋅Cv⋅ 10.2⋅ ∆P … l/min
• Formula based on effective area (Smm2)
Q=0.8⋅S⋅ 10.2⋅∆P …… l/min
Q : Flow rate (l/min)
∆P: Pressure differential (P1– P2)
P1 : Upstream pressure (MPa)
P2 : Downstream pressure (MPa)

Wiring
Conduit terminal
In the case of the conduit terminal, make connections according to
the marks shown below.
Caution
1. As a rule, use electrical wire of 0.5 to 1.25mm2
or larger for wiring.
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.

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. Maintenance should be performed 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. Replace strainers when the amount of pressure drop
reaches 0.1MPa.
4. Flush drainage from filters regularly.
2. Storage
In case of long term storage after use with water, first
thoroughly remove all moisture to prevent rust and
deterioration of rubber materials, etc.
