Caution
PRECAUTION
Be sure to read before handling.
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 ISO44141), KS B 63762) and other safety regulations.
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, this could result in serious injury or loss of life.
1) ISO 4414: Pneumatic Fluid Power-Recommendations for the application of equipment to transmission and control systems.
2) KS B 6376: General Rules for Pneumatic System
1. The pneumatic equipment shall be selected by pneumatic system designers or professionals.
The person who decides specications has a responsibility for the performance and safety.
2. Only trained person should operate pneumatically operated machinery and equipment.
Compressed air can be dangerous if an operator is unfamiliar with it.
Assembly, handling or repair of pneumatic systems should be performed by a trained and experienced operator.
3. Don't remove components until safety is conrmed.
1) Inspection of machinery and equipment should only be performed after conrmation of safe locked-out control
positions.
2) When equipment is to be removed, conrm the safety process as mentioned above. Cut the supply pressure for this
equipment and exhaust all residual compressed air in the system.
3) When restarting, take measures to prevent shooting-out of cylinder piston rod, etc.
4. Take care if the product is to be used in any of the following conditions.
Please feel free to contact us if you have any questions.
1) Conditions and environments beyond the given Specications, or if product is used outdoors.
2) Installation on equipment in conjunction with food and beverages, medical equipment, vehicles, nuclear energy,
railway, airplane, emergency stop circuits, press clutches, brake equipment or safety equipment.
3) An application requiring special safety.

Valve Operation
1. Actuator drive
Take appropriate measures to prevent potential danger caused by
actuator operation when an actuator is to be driven using a solenoid
valve.
2. Intermediate stopping
Accurate stop of the piston in a predetermined position is not possible
due to the compressibility of air when a 3-positon closed center valve
is used to stop a cylinder at a intermediate position.
Furthermore, it may not be possible to hold a stopped position for an
extended length of time since valves and cylinders are not guaranteed
for zero air leakage.
3. Effect of back pressure
You need to be careful when using valves on a manifold because
actuator malfunction due to back pressure may occur.
Your special attention should be taken when using a 3-postion
exhaust center valve or driving a single acting cylinder.
Implement countermeasures such as the use of an individual exhaust
spacer assembly when there is a danger of back pressure.
4. Since valves are subjected to air leakage, they cannot be used
for applications such as holding pressure.
5. Can't be used as an emergency shutoff valve, etc.
6. Release of residual pressure
Provide residual pressure lease function for maintenance purposes.
Special consideration should be given to the release of residual
pressure between the valve and cylinder in case of a 3-position
closed center type valve.
Installation
1. Momentary energization
If a double solenoid valve will be operated with momentary
energization, it should be energized for at least 0.1 second.
2. Leakage voltage
1) Residual leakage voltage of DC coil must be or less than 2%
1. Conrm the Specications.
Don’t operate at pressures or temperatures beyond the range of
specications because this can cause damage or malfunction.
PRECAUTION: Valve
Be sure to read before handling.
Air Supply
1. Use clean air
Use clean air which doesn't contain chemicals, synthetic oils
containing organic solvents, salts or corrosive gases etc., because
this can cause damage or malfunction.
1. Filteration to 5µm is recommended.
2. Large quantity of drainage may cause incorrect operation of pneu-
matic products as well as environmental contamination. Please
control drainage. You can use the lter with auto drainage in case
of difculty.
3. Please install a mist separator when there is a large amount of
carbon power from the compressor.
Warning Warning
Caution
Environment
1. Keep away from corrosive gas, chemical solutions, sea water, rain
and steam.
2. Avoid using in an explosive atmosphere.
3. Don't use in locations subject to vibration or impact.
4. Avoid direct sunlight.
5. Shield radiated heat generated by nearby heat sources.
6. Use a protective cover when installed in a place where a drop of
water or oil will splash momentarily.
7. Please install a silencer on the exhaust port in a dusty place.
Warning
Caution
Caution
Lubrication
1. No further lubrication is required because valves are prelubricated.
2. Please use turbine oil ( ISO VG32 or equivalent to ) if lubricant is
required. Once lubrication is applied, it must be continued because
the original lubricant may be eliminated.
Caution
5

PRECAUTION: Valve
Be sure to read before handling.
Piping
Low temperature operation
1. Before piping is connected, remove chips, cutting oil and other debris
form inside the pipe.
2. When using the Teon tape, ensure that about 1.5~2 threads are left.
3. When using 3-position closed center type, make sure piping leakage
does not occur between valve and cylinder.
4. Clamping torque
Port size Appropriate clamping torque N·m (kgf·cm)
M5 1.5~2 (15~20)
Rc(PT) 1/8 7~9 (70~90)
Rc(PT) 1/4 12~14 (120~140)
Rc(PT) 3/8 22~24 (220~240)
Rc(PT) 1/2 28~30 (280~300)
Rc(PT) 3/4 28~30 (280~300)
Rc(PT) 1 36~38 (360~380)
Using 3-port valve
Maintenance
Avoid ambient temperatures outside the range prescribed in the
Specications. At low temperatures, appropriate measures should be
taken to avoid solidication of freezing of drainage and moisture, etc.
If you block one side of valve port (A, B) with plug, you can use the
valve as 3-port valve with N.O. (Normally Open) or N.C. (Normally
Closed) type.
It is convenient when you need 3-port valve in the manifold blocks.
1. Drainage removal
Remove drainage regularly from air lter.
1. When equipment is removed, rst conrm that measures are in place
to prevent dripping of work pieces and run-away of equipment, etc.
Then cut the supply pressure and power, and exhaust all compressed
air from the system using its residual pressure release function.
When the equipment is to be started again after remounting or
replacement, rst conrm that measures are in place to prevent
lurching of actuators, etc., and then conrm that the equipment is
operating normally.
2. Although don't use frequently, operate the valve regularly to prevent
malfunction.
when switch is OFF.
2) When using a C-R element, there might be a chance to increase
the leakage voltage.
3. Low temperature operation
Avoid ambient temperatures outside the range prescribed in the
Specications. At low temperatures, appropriate measures should be
taken to avoid solidication of freezing of drainage and moisture, etc.
4. Operation for air blowing
You should use external pilot type or direct solenoid operated type
when using solenoid valves for air blowing.Also, supply compressed
air within the pressure range prescribed in the specications,
especially for an external pilot type.
5. Mounting
In case of a single solenoid valve, the mounting orientation is
unrestricted. Double solenoid or 3-posiotn valves should be
mounted so that the spool is horizontal. Mount valves so that the
spool is at a right angle to the direction of vibration in a place where
vibration or shock exists.

Lamp and surge voltage suppression Power supply time
Classication by the existence of noise suppressor
1. Do not make a megger test between lead wires.
2. 12 and 24 VDC solenoids will not shortout even with wrong
polarity. However, solenoids with surge suppression will not
operate.
3. Single solenoid
If circuit current leakage is experienced, the valve may not turn
off. Ensure that current leakage is below the maximum allowable
leak rate.
4. Double solenoid
Do not apply power to both solenoids simultaneously. The valves
may be put into a neutral state.
Plug connector type (For SV 50, 100 series)
DIN terminal type (For all SV series)
When using a double solenoid type with momentary power source,
make sure the power supply time more than 0.1 second.
Solenoid with noise suppressor is eligible for interface of CPU, PC, and
micom etc. because it has a element suppressing the max. voltage
