The solenoid uses a special construction, with
an extremely small 0.56mm [0.022in.]
armature stroke, and therefore consumes little
electric current.
In addition, the AC type uses a silicon diode for
half-wave rectification that ensures extremely
stable operation.
Moreover, since there is no in-rush current, the
capacity of electrical equipment can be reduced,
decreasing the amount of heat generated in
high-frequency operations. The coil will not burn
even if the armature unactuates under some
abnormal situation.

The coil is a vacuum epoxy resin impregnated
mold, for high resistance to heat, cold, humidity
and vibration, and completely eliminates wirebreak failure. Moreover, the iron core is not a
laminated sheet, but rather machined a single
block, for superior mechanical strength against
heat or shocks, and endures a long time
without deformation or breakage.

●Compact and light
●No need for lubrication
A poppet construction with unique and
compact design. The body is made of light
aluminum alloy.
Entering foreign materials into a valve’s
interior, not using for a long period, etc., could
cause the main valve piston to stick. This is
not a problem at all with the poppet type
round solenoid valves.
With virtually no
sliding parts, there is
no need for lubrication
except for a few
specific models.
This means no breakdowns, caused by
such as galling due to
insufficient lubrication.
It can also eliminate
periodic lubrication
expenses.
●Any mounting direction acceptable
●No leakage due to foreign materials in the media
While some valves will require that the
mounting direction is vertical or horizontal to
operate, the round solenoid valve remains
undisturbed regardless of whether the
direction is off to some degree, upper or
lower, or left or right.
While foreign materials
in the media can often
cause leaks, the round
solenoid valve uses
rubber to absorb the
distortions caused by a
certain volume of
foreign materials to
prevent leaks.

While the standard specifications are AC100V
and 200V, many other voltages are available,
as shown in the appended table. Many of
these voltages are common to each model,
and therefore offer interchangeability, good
quality control and stable quality.
All solenoids, including the DC types, have the
same shape and same dimensions.

The poppet and stem section have low mass and
the stroke is short, helping to reduce inertial force,
while the synthetic rubber flexibly absorbs impacts,
enabling excellent durability in continuous, highfrequency operations.
●Extremely long operating life
With virtually no sliding parts, and with the
large elastic capacity of the synthetic rubber
used in the stem, the high capacity design
eliminates any concerns about wear or
damage. The operating life is therefore
extremely long, and all models except a very
few can last over more than 10 million
operating cycles.

Solenoid Types and Operating Principles
(While the schematic diagrams show the direct-acting 062 series, 3-port valve, the basic construction of the solenoid is the same for
the 4-port valve and for the pilot section of the indirect acting valve.)
Single solenoid type, normally closed
(E1 type, NC)
Symbol
1. When de-energized, air coming through port P is
closed by the poppet at P, and air at A goes to
port R.
2. When energized, the P side poppet opens and
the R side poppet closes, so that the air flows
from P to A.
3. When power is cut off, the armature is pushed
downward by the armature spring to change the
valve to a de-energized condition.

closes, so that the air flows from P to A.
3. Even if power to the S-C terminal is cut off, a
strong residual magnetic force maintains the
previous position.
4. When power is supplied to the R-C terminal, the
residual magnetic force disappears, and the

1. When the S1 solenoid is in an energizing
condition, the air coming from P is blocked by
the poppet at P, and air flows from A to R. This
condition is firmly maintained by the air pressure
applied to the poppet at P.
2. When the S2 solenoid is energized, the P side
poppet opens and the R side poppet closes, so
that the air flows from P to A. This condition is
firmly maintained by the air pressure applied to
the poppet at R.
3. While the solenoid is “momentarily energizing
holding type” increasing residual magnetism in
addition to the normal continuously energizing
type, air pressure applied to the poppet
guarantees the holding position in the case, as
well.

●When connecting 2 or more valves in
parallel, use the black lead wire for common
connections of the AC type. A diode is
connected to the black lead wire for the AC
type. No diode is in the DC type, so the
wiring has no polarity.

●For the 2, 3-port valve, energizing the S1
solenoid in the diagram (the set side) opens
the valve, while energizing the S2 solenoid
(reset side) closes it.
●For the 4, 5-port valve, energizing the S1
solenoid opens the A port, while energizing
the S2 solenoid opens the B port.
●For connections of 2 or more valves in
parallel, or for instructions for wiring
connections with other inductive loads, see
p.883.

●No diode is equipped with either the AC or DC type,
so the wiring connections have no polarity.
●The lead wire color coding and instructions of

●While the energizing time required for switching the
valve is about 50ms, air pressure is required to
maintain that condition. For this reason, continue
energizing until exhaust is complete (or when
operating a cylinder, until the operation is
complete).
●Hold the continuous energizing time to 5 minutes or
less, and ensure that the de-energized period is
longer than the energizing time.

Explanation of Keep Solenoid
Features
While the conventional self-holding type solenoid valve employs 2 solenoids, this keep solenoid type achieves the same operation with just 1
solenoid.
Can firmly maintain both the ON and OFF positions with just momentary energizing.
Holding force is strong, achieving superior vibration and shock resistance in any directions.
Vibration resistance is more than 107.9m/s2{11G} and shock resistance is more than 294.2∼392.3m/s2{30∼40G} for the direct acting type, and
980.7m/s2{100G} for the indirect acting type. (Shock resistance for the ordinary microswitch is about 294.2m/s2{30G}, and about 49.0∼
196.1m/s2{5∼20G} for the relay.)
No need to worry about burning even with continuous energizing.
Moreover, burning will not occur even if the set signal and reset signal are applied at the same time.
Construction and operation
The diagrams show the direct acting type (or pilot section for the indirect acting valve).
Operation under the set signal
Operation under the reset signal
When the ON signal is excited (for 0.05s or more) to the S-C (set
side) terminal, as shown in Fig. 1, the solenoid is energized by halfwave rectification, and the armature is attracted (the direction of
current flow and the magnetic poles are as shown in the diagram).
Then, the armature keeps its position by residual magnetic force
even after the ON signal is turned off.
When the OFF signal is excited (for 0.05s or more) to the R-C (reset
side) terminal, as shown in Fig. 2, the current reduced by resistance
flows in the direction opposite to the set direction, the residual
magnetic force suddenly vanishes, and the armature is returned to its
position by a spring. In other words, turning this solenoid valve ON
and OFF is achieved by momentary energizing alternately to S-C and
R-C.

Wiring instructions
●When activating 2 or more valves simultaneously
When the ON and OFF operations are reversed, use different connections to link the S and R
terminals, as shown in the diagram at the left. When the S and R terminals are connected into
their same respective phases, there is no limit to the number of units that can be connected in
parallel.
<The reason>
When the A-1 contact is turned on, current flows along the R-C on Valve 1 and the S-C on Valve 2, and
they are both activated normally. The C side is the positive (+), however, the current flows along the
dotted lines and causes resets or vibrations, even when a set signal has been excited to valve 2.
Correct wiring
● When using a neon lamp
Install a diode and a surge absorber on
the R (reset) side, as shown in the
diagram.
Use the diode, with which dielectric
voltage is about 3 times as high as the
power voltage. If the diode is not
installed, or if it is connected in the wrong
direction, both neon lamps will light up
when the set signal is excited.

Precautions (Keep solenoid)
1. Note that the keep solenoid valve cannot be used with solid state type relays with leakage current.
Because the solenoid’s reset current is so small that the relay leakage current alone can reset the solenoid after it has been set.
2 Note that exciting the set and reset signals at the same time can cause vibrations.
3. While the valves work under normal usage and environments in most applications, avoid using in locations subject to harsh vibrations or to strong
magnetic fields.
4. While the direct acting type maintains the ON or OFF position regardless of the presence or absence of an air supply, caution should be
exercised that the indirect acting type switches the stem to the OFF position when the air supply is cut off.
5. Use a fingertip to operate the manual override. Note that the manual override will not activate when the valve is set to the ON position. Operate
the manual override after exciting the reset signal to demagnetize and set the reset signal to OFF, such as in a test operation .
Safety Precautions (Round type series solenoid valves and explosion proof solenoid valves)
Warning 1. When mounting a valve inside the control panels or when an operation requires long energizing periods, provide heat radiation
measures to ensure that the ambient temperature always remains within the temperature range specifications. For long-term
continuous energizing, consult us.
2. Always check the Catalog, etc., when carrying out wiring and piping of products to ensure that the connections are correctly
done. Wrong wiring or piping could result in abnormal operation to the actuator, etc.
3. The solenoid valve’s silicon diode could be damaged by surge voltage when a large inductive load is used on the same power
supply. Either change to a separate power supply, or install a surge absorber to protect the unit. Solenoids with surge
suppression are also available. Consult us.
Caution For locations subject to water or to large amounts of dust, use a cover, etc., to protect the valves. Also, attach a muffler, etc., to
the R port to prevent dust from entering. Entering water or dust could result in short-term functional shutdowns, sudden drops in
performance, or a reduced operating life.
Attention 1. Use clean air that does not contain degraded compressor oil, etc. and install a filter, etc., close to solenoid valves to remove
dust or collected liquid.
2. Ensure that the piping port on the supply side has at the same area or larger than the solenoid valve’s effective area.
3. When using an indirect acting valve, use a stop valve between it and the pressure source. When the stop valve is opened
before the pressure reaches the minimum operating pressure, the indirect acting valve could fall into a neutral position.
(All solenoid valves in the 250 series and up are indirect acting valves.)
4. When connecting 2 or more AC type solenoid valves to the same power supply, connect the same color lead wires.
5. Since a diode is equipped with the AC type solenoid valve, the solenoid may sometimes not turn on with the solid state-type
relay (SSR) with zero-cross function. For this reason, pay attention before use to the ratings and precautions for use of the solid
state-type relay.
In the Catalog, Class 1 of the recommended oil “Turbine Oil Class 1 (ISO VG32)” signifies “non-additive,” while VG32 signifies
“viscosity.” The previous notation of “Turbine Oil #90” has been changed.

Speed Controller Mounting and Adjustment Instructions
Mounting instructions Differs from the 125 series.
Adjusting instructions
1. Return the adjusting screws 1 and 2, without excessive force, to their original
positions (the A dimension in the right figure of about 6mm [0.24in.]).
2. Screw the plug in until the dimension from the plug end surface to the lock nut
becomes 3∼3.5mm [0.118∼0.138in.] (the B dimension in the diagram) and align
the plug’s groove for screwdriver to be vertical, and then secure the lock nut in
place.
(Since the brake ring serves as the lock ring for the adjusting screws, it can still be
used even if the outer surface is scratched.)
3. Screw in the adjusting screws until the end rubber of the adjusting screws lightly
strikes the seat surface (the A dimension at this time is 2.5∼3mm [0.098∼
0.118in.]), and then return 1 rotation.
Tightening the adjusting screw throttles the exhaust and reduces the cylinder speed.
Returning about 0.5mm [0.020in.] (1 rotation) from the fully tightened position leaves
it virtually full open, and any further return rotation will not increase the speed.
Do not return more than 6mm [0.236in.] (the A dimension in the diagram) from the
plug end.

Mounting instructions Differs from the 062 series.
Adjusting instructions
1. Leave adjusting screws 1 and 2 protruding about 4mm [0.16in.] from the plug (the
A dimension in the right diagram). This position is where the adjusting screw’s
end rubber comes in contact with the brake ring.
Tightening the adjusting screw throttles the exhaust and reduces the cylinder speed.
Returning about 0.5mm [0.020in.] (1 rotation) from the fully tightened position leaves
it virtually full open, and any further return rotation will not increase the speed.
Do not return more than 5mm [0.20in.] (the A dimension in the diagram) from the
plug end.
2. Screw the plug about 2 rotations into the valve body, and then return adjusting
screws 1 and 2, without excessive force, to their original positions (the A
dimension in the diagram of about 5mm [0.20in.]).
At this time, the adjusting screw’s end rubber makes the brake ring expand
outward and comes into contact with the plug end.
3. Screw the plug in until the dimension from the plug end surface to the lock nut
becomes 2.5∼3mm [0.098∼0.118in.] (the B dimension in the diagram), align the
plug’s groove for screwdriver to be vertical, and then secure the lock nut in place.
(Since the brake ring serves as the lock ring for the adjusting screws, it can still
be used even if the outer surface is scratched.)
4. Screw the adjusting screws in until the end rubber of the adjusting screws lightly
strikes the seat surface (the A dimension at this time is 3∼3.5mm [0.118∼
0.138in.]), and then return 1 rotation.

Operation principles
1. Energizing the solenoid S1 in the intermediate
stop condition causes the poppet to fall, and the
pilot valve A"', and the main valve poppets A'
and A" move to the left.
As a result, the P port air flows to the B side,
the cylinder piston moves to the right, and the
head side air is exhausted from the R port.
3. Energizing both solenoids S1 and S2
simultaneously causes the 1. and 2.
description at left to occur at the same time,
with the air coming from the P port flowing to
all of the B, A and R ports. In this case, be
aware that the cylinder thrust is almost
completely lost, and a large volume of air is
exhausted from the R port.

2. When the solenoid S2 is energized, the B side
pilot valve and main valve poppet move to the
right, as in the 1. above, and the piston moves
to the left.
Application Example (3-position solenoid valve closed center)
Safety measures in an emergency
Change in cylinder stroke
1. Pushing up wood material
Dangerous when using the
2-position solenoid valve,
due to power outage or
emergencies. For instance, a
3-position solenoid valve
sudden fall will occur.
2. Robot arm operation
3-position solenoid valve
When using the 2-position
solenoid valve, the arm
retracts during a power
outage, causing damage to
the machinery and/or
workpieces.
3. Container transfer
Example shows a container
being filled with liquid and
transferred to the next
process. The 2-position
3-position
solenoid valve
solenoid valve can cause a
sudden return to the original
position during a power
outage.
1. Opening and closing
door of heat treatment
furnace
The workpiece can be
retracted or pushed inward
without opening the door
wider than necessary.
929
2. Height adjustment of
sealing roller
Even with boxes of different
heights, the roller position
can be changed to perform
sealing operations.
Note: When using for long
periods at a set height,
adjustment against drift
is required.

a:Overrun distance
b:Repeatability
Note: Cylinder sliding resistance, etc., leads to quite large speed variations. In addition, vertical load
can generate “vibration (damping vibration)” until stopped. Use this table as a guide.
How to read the table
For example, when the 253-4E2 type solenoid valve is used, and stops an operating φ80 [3.150in.]
cylinder with no load and the horizontal operating speed of 200mm/s [7.9in./sec.], then it overruns by
about 5mm [0.197in.] beyond the limit switch that sent the stop signal when it actuates the switch, until
stopping.
When the operation is repeated, then it stops within ±1mm [±0.039in.] of the range, or in other words,
4∼6mm [0.158∼0.236in.].
Handling Precautions
For improving stopping accuracy
For safety
●Keep the piping short, and ensure that the fittings, etc., do not leak.
●When a load has thrust force (vertical loads, etc.), it can momentarily
move in the opposite direction when switching from forward to reverse. At
this time, installation of a check valve just prior to the valve’s P port can
prevent this phenomenon.
●Use a bore size with plenty of margin for the required thrust. A suitable
level is 2∼4 times the thrust.
●Avoid selecting a valve that has too large a capacity for the cylinder bore
size (see the table for appropriate cylinders).
●Do not use too fast of a cylinder speed.
●Use a speed controller valve built-in type (Order Code: -70). Mounting a
speed controller between the cylinder and valve may result in a failure to
stop, or in a bad response to a stop.
●Cannot be used in combination with the hydro checker.
●When left unused in an intermediate position for a long period, the air
inside the cylinder could often leak out when operated again. In this case,
it is impossible to control the speed, and high-speed cylinder operation is
dangerous.
Therefore, after completion of operations, or after having left the unit for
long periods or when exhausted the pressure from the P side, use the
following sequence to commence operations. Also take safety circuit
measures into consideration:
1. Always position the piston rod either to the extended or to the retracted
end after operation.
2. The next time the piston is moved, send a forward signal when the piston
is stopped at the extended end, and send a backward signal when it is
stopped at the retracted end.
3. Resume normal operations.
●For handling precautions common to the solenoid valves round type
series, see p.884.

Explanation of Explosion Proof Code [d2G4] and the Usable Range
Explosion proof codes for the explosion proof solenoid valves are determined by the construction and the applications.
The Koganei explosion proof solenoid valve’s explosion proof code is “d2G4.” In other words, the construction is “d: Flameproof construction” that can be used in
Type 1 and Type 2 dangerous locations, and that can withstand explosive gases that reach dangerous densities up to “2: Gas with explosion class up to 2,” and
“G4: Gas with ignition temperature up to G4” level.

Wholly sealed construction that can withstand
the pressure even if explosions occur inside
the container, and that will not allow ignition
of explosive gases outside of the container.

Construction that is certified by authorized
institutions in ignition tests, etc., to prevent
the threat of explosive gas ignition due to
sparks, arcs, or heat generated by accidents

Type 0 location
Type 1 location
Locations that continuously generate
dangerous ambient atmosphere, or threaten
to do so, and where explosive gas
concentrations are either continuously
present or present for long periods, and
exceed explosive limits.
Locations where dangerous ambient atmosphere
threaten to be generated in normal conditions, and
where the following conditions prevail:
(1) Locations where explosive gases threaten to
be accumulated in dangerous concentrations
in normal conditions.
(2) Locations where repairs, maintenance, or
leaks often threaten to let explosive gases be
accumulated in dangerous concentrations.
Type 2 location
Locations where dangerous ambient atmosphere
can be generated in abnormal conditions:
(1) Locations where inflammable gases or
inflamable liquid are handled on a normal basis,
but are enclosed in sealed containers or
facilities, and dangerous concentrations are
threatened only when an accident or erroneous
operation, or damage to the containers or
facilities, causes the gases or liquids to leak.

Operation of Manual Override
Handling Precautions
Removing the lock pin on the manual override and
pulling out the manual override button causes the
valve to switch.
Pulling it all the way out maintains the switched
position, while pushing it in restores it to the normal
position.
When not using it, always secure it in place with
a pin.
●Use only within the usage range detailed in “Explosion proof construction type d2G4.”
●Always firmly tighten all lock tightening portions.
●Do not apply tension force to the lead wire connecting portion and firmly secure the lead wires in
appropriate locations.
●Use lead wires suited to the lead wire outlet.
●When releasing the lock tightening portion, shut off the power to ensure a non-voltage condition.
●When activating the solenoid, always leave the manual override lock pin in the inserted position.
●See the Safety Precautions on p.884.
