9Explosion-proof Solenoid Valves and Valve Systems

General Handling Instructions and Precautions
Please read the following general handling instructions and precautions carefully before ordering solenoid
valves.

Safety Precautions
Warning

References:

JIS B9702:
Safety of machinery- principles of risk assessment
JIS B8370:
Pneumatic fluid power -general rules relating to systems

Following information is based on a risk assessment for Konan products. Each section provides information essential forsafe operation of the products and prevention of risk and damage that may affect operators. Please read carefully.

1.Selection of solenoid valves

Solenoid valves are used to activate actuators by switching air flow in apneumatic system with electrical signals.
In order to ensure safe system operation it is significant to selectappropriate valve type. Therefore the entire pneumatic system designer
should determine the solenoid valve taking into consideration therequired operation, performance, and countermeasure to system failure.
Electric components need to have explosion-proof construction
respectively depending on the purpose of use, type of explosive gas
and dangerous place where the components are used. As electriccomponents having explosion-proof construction show where thosecomponents can be used by symbols, check the symbols to select asuitable component.

2.Solenoid valve installation

As pneumatic components are operated with compressed air, sudden
blowout, unintended operation by residual air inside actuators (burstingout of a cylinder etc.), and other risks should be taken into account.
A sufficiently trained person should be responsible for installation andmaintenance of a solenoid valve.

(Konan provides training for operation and maintenance of pneumaticcomponents. Feel free to contact our sales personnel for details.)
This series of solenoid valves is explosion-proof type.
For actual handling of the valves, personnel with sufficient knowledge
about explosion-proof wiring should be responsible.

3.Maintenance of solenoid valves

Make sure before maintenance of solenoid valves that the pneumatic
system is in a safe position or the system is mechanically fixed.
Compressed air remains as energy even after shut off of air supply.
Close the air supply line and exhaust air inside the pneumatic circuit at
the same time.Carefully read the details in “7. Maintenance” describedlater.

4.Solenoid valve installation site

For use of solenoid valves under following conditions sufficient safetymeasure should be taken. Consult us for details.
1) Operating conditions are not within the specified range.
2) Significant risks for users, properties, or environment are anticipated.
Eg: Use for nuclear power plants, vehicles, medical components, etc.

Users Instructions
Caution 1.Transport of solenoid valves
1) A solenoid valve is supplied in a package. Do not treat the package
roughly to prevent valve deformation and other damage that may
result in valve operational failure.
2) Plastic plugs are attached to the valve connection ports to prevent
dusts and rusts from entering the valve during transport or storage
before installation. Do not remove the plugs until immediatel
before piping.

Caution 2.Storage
1) Installation site
Transport a valve to the specified site just before installation. If thevalve is to be stored at the installation site, keep it packed andprotect from wind, rain, and dusts.
2) Storage
If a valve is to be stored for more than 1 year, keep it packed.
Long-term storage may result in sticking of packings. In such caseconduct pre-conditioning operation of the valve before regular use.
After a long period of storage, aging, constriction, or deformation of
packings would be a concern. Consult us for use of the valves after
long period of storage.

Caution 3.Surrounding environment

101) Vibration/shock
Solenoid valve is a complex component. Exposure of the valve toexcessive shock or vibration may cause operational failure, looseningof clamps, or early wearing of spool packings.
Make sure at installation of the valve that the valve is not in line withthe direction susceptible to vibration/shock.
2) Surrounding environment
Environment surrounding a valve should be considered carefully.

Avoid places where the valve is exposed to rain and wind, salt air,corrosive gas, chemical fluids, seawater, steam, etc.
3) Ambient temperature
Sufficient care should be taken for ambient temperature as well as
fluid temperature. Even if a valve is installed in a cool place, whenheated air inside a cylinder under high temperature environment isexhausted through the valve, it may cause deterioration of packings
or valve operational failure due to thermal expansion of the internal
components.
4) Breathing hole
The main valve and pilot solenoid valve are equipped with abreathing hole required for operation. As it is possible thatwater, foreign materials, etc. enter through the breathing hole, takemeasures by adjusting the attachment position, adding a cover, etc.

Caution 4.Piping
1) Disposal of drains
For use of a valve at lower limit of working pressure, care should
be taken for lubrication, disposal of drains, and supply air volume.
(Inlet port should be as large as possible. If possible install an air
tank in front of the valve.)2) Compressed air
Air supplied to a valve should be filtrated by air filter with nominal
filtration range of no more than 40μm to avoid excessive drain
or oil. Contaminated air may cause deterioration of packings andother components, which leads to extremely short life of the valve
or early operational failure.In the case of intrinsic safety solenoid
valves,use air filters less than 5μm.
In the case of using air whose dryness is high (dew point is -40°C
or less), it is possible that shortage of lubricant occurs at an earlystage, which shortens the service life. Consult with our sales
personnel.
3) PipingDo not remove plastic plugs attached to the valve connection ports
until immediately before piping in order to prevent dusts and rusts
from entering the valve during transport or storage before
installation. For steel tube piping make sure to use galvanized pipe.
4) Pipe narrowing
Do not narrow part of valve inlet ports. Especially when vinyl orother resinous tube is used for piping and air flow path at the tube
joint is extremely narrow, air flow rate decreases and thus
operational failure may occur. Sufficient care should also be taken
when using copper tube joint and rubber hose joint.
5) Pipe length
If cylinder speed is adjusted by reducing air exhausted from a
5-port solenoid valve, confirm the limit of the air reduction. If pipe
volume between the solenoid valve and the cylinder is large,
favorable speed control cannot be achieved. Make sure that thepipe volume / cylinder volume is not more than 0.1.
6) Pipe cleaning
After piping is completed, clean the pipe by air flushing. Use clean
air for fluid, as dusts and drain in the fluid cause significant harm to
the valve function and shorten the valve life.
7) Piping connection
Make sure to perform correct piping connection.
As pneumatic solenoid valves make significant noise at air
exhaustion, use silencer or other means to absorb noise.
Konan provides silencers that meet various types of solenoid
valves as well as silencers incorporating throttle valve.
8) Pipe screwing
When a pipe or a nipple is screwed to a solenoid valve, up to
4 or 5 threads should be screwed for 6A to 25A (Rc1/8 – 1) port
size. Any forceful screwing beyond this may result in cracking of thevalve body or leakage/malfunction. Care should also be taken forcontamination with fragments of sealing materials. In the case of
direct piping type, make sure not screwing up mounting screw tootight at valve installation.
9) Piping of manifold type solenoid valves
Manifold type solenoid valves should be operated by sequencecontrol of individual valves in principle. If 2 or more valves areoperated simultaneously, inlet supply pressure drops or supply
pressure volume to loading components decreases. Up to 3 units
can be operated simultaneously. Inlet port and exhaust port are atboth end of manifold base to enable piping from either direction.
Seal unnecessary ports with plugs. For accomplishment of
accurate operation piping at both end of manifold base (2 sites) is
recommended.

Caution 5.Lubrication
Explosion-proof pneumatic solenoid valves can be used without
lubrication. If lubricating oil is to be used, care should be taken for theoil quality. Packings incorporated in the valves can contribute to stable
valve operation only with quality mineral oil. Inappropriate lubricating
oil deteriorates sealing quality. Especially use of spindle oil oftencauses expansion of packings. Also make sure to select oil that does
not emulsify with drain. JIS K 2213 (ISO VG32 or VG46) type turbine
oil is recommended for lubricating oil.
After lubrication do not use the valve without lubrication or the valve
life may become extremely short.

Caution 6.Wiring
1) Explosion-proof wiring
For lead-in of conductors into the terminal box, follow the"Recommended Practices for Explosion-protected Electrical
Installation in General Industries" (issued by the National Instituteof Occupational Safety and Health.)i) Conduit tube type

Use thick steel conduit and screw 5 or more threads at the screw
joint. As the explosion-proof performance depends on thescrewing precision, care should be taken for conduit installation.
Elbow, flexible, or union joints to be used should also be
explosion-proof type.Konan conduit type screw is G1/2.
ii) Pressure-resistant packing type
Use pressure-resistant packing type connector when performing
cable wiring. (Approved pressure-resistant packing typeconnector should be used. Use the connector attached to thesolenoid valve.)
Before wiring, make sure that cables conform to the cable size
described on the products.
2) Applied voltage
Do not apply voltage with the terminal box opened.Check the valve
nameplate and apply specified rated voltage. Use of the valve withinappropriate voltage may result in coil damage or valve operational
failure. Use the valve after checking if voltage fluctuation is withinallowable range. If the valve is used with voltage not within thespecified range, solenoid burnout and other failure may occur. The
allowable voltage range means that instant valve operation can be
performed without problem within the range, not that the valve canbe continuously operated within the range.

Warning 7.Maintenance
Use conditions of solenoid valves differ depending on users.
The complying method varies depending on users, for example,
whether preventive maintenance or breakdown maintenance is
employed. The maintenance method is different depending on use
conditions and importance of facilities. From the above situation, we
propose recommended replacement intervals from the standpoints of
preventive maintenance.
1) Maintenance should be performed in accordance with themaintenance manual.
As a pilot solenoid valve is an explosion-proof component, do
not disassemble it. Disassembly may impair the explosion-proof
performance, resulting in accidents. When replacing a pilot solenoid
valve, use a finished part.
If it is necessary to disassemble pilot solenoid valves formaintenance,
etc., consult with our sales personnel.
2) Follow the below steps when uninstalling a solenoid valve.
i) Shut off supply pressure.
ii) Exhaust residual pressure inside pneumatic circuit.
Compressed air remains as energy even after shut off of air
supply. Exhaust pressure inside the pneumatic circuit using
residual pressure exhaust valve, relief function of a regulator, or
drain cock of an air filter.
iii) Shut down power source.
Not only disconnect the solenoid valve side terminal but also turnoff the power source.
iv) Uninstall the valve.
3) Operation frequency
Explosion-proof pneumatic solenoid valves are soft seal spool typesolenoid valve series using squeeze packings. According to the JIS
standard, minimal operation frequency of this type of valve is
specified as once in 30 days.
For safety maintenance should therefore be performed once in 30
days.
4) Push button
If a push button of a solenoid valve is pushed, the valve coil isenergized. Care should be taken so that a third party does not push
the button without discretion. A cap with which a push button part iscovered protects a push button from being operated by mistake
and water from intruding into the inside of housing. Do not remove
the cap except when it is necessary to operate the push button.

● For the prevention of mis-operation, a standardized cover cap is provided on the terminal unit.
● The enlarged wiring space of the terminal block permits 270℃ rotation by single bolt operation in
the same way as for solenoid housing,thus significantly facilitating the explosion-proof electrical
work to be carried out with extreme care.

● The solenoid housing may rotated by 360 ℃ ,thus permitting the cable outlet to be installed
optionally in 3-dimensional direction.
● The installation work can be performed readily by the use of the use of a single bolt.

● The use of a magnet-latched solenoid allows two coils
to be housed within a single casing,thus reducing thenumber of cable outlets to one.
● The moving iron core attracted and retained to the
fixed iron core（1）by the magnetic field（1）of thepermanent magnet is freed from the magnetic field（1）and attracted to the fixed iron core（2）when the coil（2）is energized. The moving iron core is retained by themagnetic field（2）even when the coil is de-energized.
● When the coil（1）is energized,the moving iron is freed
by the magnetic field（2）and attracted to the fixed ironcore. The moving iron core is retained by the magnetic

Magnetic field（2）Fixed iron core（1）● simple,easy-handling,water-proof,pressure-resistant packing type cable gland is provided as astandard component.

● Simple push-button operation permits direct manual control of the moving iron core. The manual
operation is practicable irrespective of energization or de-energization.
● To take full advantage of the features of the magnet-lached solenoid,manual locking is effected by
the magnetic circuit of permaned magnet.
（Vibration resistance and impact resistance of the manually-operated lock are not less than 3G and 7G respectively.）● An innovative lubrication-free slide selector applied with high-hardness ceramics isincorporated,thus providing a semi-permanet durability and the most suitable application for high/low frequency operations.

Lubrication of the solenoid valve main body is not needed, but when lubrication of other devices
is needed, use JISK2213 additive turbine oil ISO VG32 or VG46.
When operating two or more solenoid valves of manifold type simultaneously, note that that the
P port (supply) pressure may be lowered, or that the flow rate to the load device may decline. For
obtaining a more secure operation, the both-end P and R port piping is recommended.

Model List〔Compact explosion-proof solenoid valves〕
Pilot valve● This is a poppet structure few in sliding parts.
A stable operation free from sticking phenomenon for a long time is promised.
● A push button (manual operation mechanism) capable of locking is equipped as standard.

Main valve● In spite of small size, a large flow rate is realized by the main valve. A simple spool valve using an I-typering in a narrow main body is disposed rationally.
● Connection interface of the main body is available in two types. The actuator can be mounted or
mounted in a most suited manner.
(1) NAMUR standard modelThis is a five-port solenoid valve for rotary actuator operation adopting the mounting interface specified
in NAMUR standard.
(2) Direct piping typeThis is a five-port solenoid valve for connecting to the actuator by piping connection. Single installation
at a remote position, or coupling type by manifold structure may be realized.

Push-button (manual operation mechanism)● By pushing the push-button (red), the solenoid valve is actuated, and when released, it isreturned to the original state.
● When locking the push-button, use the blade of a screwdriver or the like, and turn the pushbutton to the right, and it will be locked. When turned to the left, it will be unlocked.
● When the push-button is locked, after operation, turn to the left to unlock.
(If turned while pushing the push-button, the same action takes place, and there is no problem.)

In principle, use the solenoid valve without lubrication. For working fluid, use fresh air, and do not
mix with deteriorated compressor oil or the like.

At the inlet side (P-port) upstream of the solenoid valve, install an air filter (filtration degree: 5 µ orless), and remove dust and drain.

If leaving it behind without use for 1 year or longer, check it before use.

directions without short-circuiting, while limiting theenergy transmission to the level not to ignite the explosive
atmosphere.

1. Applicable to class 0 hazardous area.
2. Only by connecting in series to the transmission circuit, the line and the device in the hazardous area can beprotected from accidents in non-hazardous area.
3. The conventional wiring system can be used in the hazardous area.
4. The intrinsic safety of control operation signal can be realized easily and at low cost.
5. SAF3-5 safety barrier is provided with a protective circuit at the input side, and if connected in wrong polarity
by mistake, the circuit will not be broken.
6. SAF3-5 safety barrier is designed in wiring and connection system by crimped terminal.
7. Explosion-proof standard: If selecting an solenoid valve of Exia II BT5, use the explosion-proof barrier in
combination with the SAF3-5, SAF100-5, or the barrier satisfying the condition specified in page D-6[When selecting other explosion-proof barriers].

Caution

1. Safety holding rating● Devices (power switch and others) connected to the explosion-proof barrier in the non-hazardous area should be free from parts
composing voltage wires exceeding 250 V (RMS) or 250 V (DC) in the ground potential in usual time or in the event of accident,
or parts supplied from such voltage wires.
● If power is supplied from the main bus, isolation from the main bus is required by means of double winding transformer, and theprimary winding should be protected by a fuse having a conforming interrupting capacity (rating).

2. Inductance and capacitance of external wiring● The wiring length (between barrier and solenoid valve) is limited by the inductance and capacitance of the wiring.
General parameters are as follows.
SAF3 − 5In case of capacitance: 100 pF/mMaximum wiring length to stay below thecapacitance allowable in external wiring

5000m

In case of inductance : 25 µH Ω /DC resistance : 40 Ω /km
Maximum wiring length to stay below the inductanceallowable in external wiring in both directions
