Solenoid Valves for Fluid Control and Valve Systems

General Handling Instructions and Precautions
Please read the following general handling precautions carefully before ordering solenoid valves for fluid control.
Following information is based on a risk assessment for Konan general purpose solenoid valves used for fluid
systems (hereafter referred to as Agvalve(s)Ah). Each section provides information essential for safe operation ofvalve systems and prevention of risk and damage that may affect operators. Please read carefully.

Safety Precautions
Warning

JIS B9702:
Safety of machinery_ principles of risk assessment
JIS B8370:
Pneumatic fluid power_general rules relating to systems

A valve is operated by switching electric signals to increase / decrease or stop/supply fluid. It is widelyused for fluid control systems in general. For safe operation of the valve, care should be taken especially forthe following points.

① Selection of solenoid valves

1.1 Applicable fluid
A valve should be used with compressed air only, except forcases where nitrogen gas tank1) is used for system inspection,
emergency measure, or portable pressure source. If highly dry
air with dew point of no more than -40℃ is to be used, makesure to use the valve with lubrication taking into consideration
the dryness measure.
For a general purpose solenoid valve (for liquid and gas fluid)
for which air is not specified as one of applicable fluids, do not
employ compressed air as a flow media. For anything unclear
regarding applicable fluids, feel free to ask our sales personnel
in the planning stage.
Note1) Be careful to avoid suffocation of operators and othersaround the valve system. For a system that uses
portable air or nitrogen tank, the High Pressure Gas
Safety Law will be applied where fluid pressure exceeds
1 MPa.
1.2 Safety of a valve
A pneumatic system may be exposed to various hazardous
environment, including those derived from the system components
as well as the condition for use and the system structure. In
selecting a valve make sure to take into consideration the valvefunction as well as safety in installation, adjustment, actual
operation, system failure, and disposal of the valve.
1.3 Electrical safety
A solenoid valve is activated by magnetic force (solenoid). Take
into consideration the following matters when selecting a valve
and electric options.
1) Dust-proof/water-proof specification Water-proof indication
should follow JIS C0920.
2) Sudden shut down of power source (power failure,emergency
shutdown, etc.)
3) Voltage fluctuation in power source and electrical surge
4) Leakage current at PLC (sequencer) power off Konan solenoid
valves are not equipped with functions that meet the following
conditions. Do not use the valves in these conditions or
employ a safe electric distribution.
1) External magnetic field effect2) Electric current from the relevant control circuit3) Lightning-induced voltage
1.4 Pilot valve
A compact size pilot valve is widely used in general, as it
switches large main valve with a small output. However, acertain inlet pressure is essential for the valve operation. For
control of minimal pressure, select a direct-acting type valve.
With optional pilot supply (separate pilot piping needed), a
pilot valve can be used even when the main valve pressure iszero.
1.5 Back pressure from exhaust port

3

References:

In some poppet valves, back pressure from the exhaust port
may affect the valve operation. There is no problem with theback pressure generated in the silencer set at the exhaust
port, but do not force to narrow the exhaust port diameter orconnect a long pipe to the port. Details of the effect of backpressure are described in a separate operation manual. For
anything unclear feel free to contact our sales personnel.
1.6 Reverse flow
Use a valve complying with the flow direction indicated with arrow
mark in the JIS figure of the catalogue and operation manual.
Safe operation cannot be guaranteed if the valve is used withreverse pressure or reverse flow. There is no problem with theslow reverse flow exhaustion during maintenance or compressor
power off. If valve operation is stopped abnormally, a failure may
occur when restarting operation due to the stop position of thevalve. If reverse flow is detected at abnormal stop or any troubleat the restart of the valve is concerned, feel free to ask our sales
personnel.
1.7 Manual operation
1) If there is a possibility that manual operation button of a valve
may be pushed unexpectedly, select a valve equipped withprotection cover.
2) If failure to unlock manual operation of a valve may cause
serious danger, select a valve without locking function.

② Solenoid valve installation

Solenoid valves have precise operational functions andare used for applications with versatile conditions andenvironment. It is therefore sometimes difficult to assume allconcerned risks or risk factors when designing a valve. In suchcases the valve function and performance may be deteriorated
in a period shorter than the maintenance period set by the
manufacturer. In order to avoid the risks, install the valve as
instructed below.
2.1 Installation site
Install a valve in a place where setting and maintenanceis easy. As a valve is often incorporated into an existing
main system, consideration for maintenance is sometimes
insufficient. Secure enough space for safety of the valve
operation.
2.2 Operating procedure
When operating a valve to activate a pneumatic cylinder andother actuators, install the components and complete piping,
and then start operation of the actuators with small load andslow speed, gradually adjusting them to rated conditions while
confirming no abnormalities or air leakage in the valve andactuators.
2.3 Bursting out of a cylinder
After installation or maintenance, supply air after confirmingthat a cylinder is in a targeted valve control position. If not inGeneral Handling Precautions
the position, the cylinder may rapidly shift to the control position.
In order to avoid this risk, installation of a slow-start valve at the
IN port of the valve is recommended.
Note) (See Section 2.4) When installing a slow-start valve
at the IN port of a pilot valve, adjust a bypass valve of theslow-start valve in order to maintain minimal operationalpressure of the pilot valve. If the bypass valve diameter isexcessively narrowed, the pilot pressure will become lessthan the minimal operational pressure, which may cause
valve malfunction.
Also, when restarting air supply, open a manual valve in ashort period of time while checking manometer to secureminimal operational pressure of the pilot valve, and thensupply air slowly.
2.4 Securing pilot pressure
Install a pilot valve taking care for the following matters.
1) Inlet pressure of a valve should be higher than the minimal
operational pressure. Especially if air supply is not enough,pressure fluctuation may occur during the valve operationand pressure may be below the lower limit of the operationalpressure.
2) If long piping is employed at the inlet of a valve or the pipe
diameter is smaller than the port diameter, pressure drop
may occur, resulting in the inlet pressure decrease.
Note: One countermeasure is to install a supplementary air
tank in front of the inlet port. In order to confirm no
decrease in inlet pressure, install a manometer aroundthe port.
3) For a manifold type solenoid valve, make sure to connect
allowable number of valves only. Simultaneous operation
with excess number of valves (more than 3 units in standard)
may cause centralized pressure drop at the manifold,decreasing the valve inlet pressure.
Note: For a manifold with two inlet ports, the number of valves
can be increased by supplying air from both ports.
2.5 Indication
If a valve nameplate cannot be seen due to installation
environment, place an alternative indication near the valve.
2.6 Residual pressure
Compressed air in a pneumatic valve system may not becompletely exhausted after the valve power shut down.
Residual pressure may cause unintended cylinder operation in
the system. A valve should be installed taking into consideration
the risks including sudden blowout of residual air.
2.7 Air exhaustion
At an exhaust port of a valve, sonic jet flow may occur,causing noise as well as damage to operator due to thefragments and dusts spread by the jet flow. If any personnel
may come closer to the exhaust port, install a silencer toavoid noise and adjust air flow.
2.8 Training
A sufficiently trained person should be responsible for
installation and maintenance of a pneumatic system. (Konan
provides training for operation and maintenance of pneumaticcomponents. Feel free to contact our sales personnel for details.)③ Maintenance of solenoid valves

Maintenance should be performed in accordance with thefollowing steps. Feel free to contact our sales personnel for
separate maintenance manual.
3.1 Daily inspection
1) Drains contained in compressed air may inhibit the valve
lubrication. Set an air filter in front of the valve and routinely
exhaust drains.aactuators.

2) During the valve system operation, check the valve visually
and acoustically for external abnormalities or noise. Checkalso the loosening of screws and air leakage from exhaust
port and piping joint without exhausting air from the system,and perform periodical inspection as necessary to recover
any abnormalities.
3.2 Periodical inspection
Following periodical inspection should be conductedby-annually or annually.
1) Overhaul should be performed after pneumatic/electric
shut-down and abnormalities recorded and repair conducted
as necessary.
2) In the 2nd periodical inspection, perform an overhaul of the
product, repair or exchange solenoid assAfy, coil, packings,
and other components as necessary. However, even before
2 years has passed, the valve that reached the specified
durable operation cycle2) should be over hauled and partsexchanged if necessary.
Note2) [Laboratory durable operation cycle]: New Magstar
414 series and heavy duty series solenoid valves:
5 million cycles
Durable operation cycle for each valve is specified in theoperation manual or drawing. This cycle is determinedbased on the Konan standard test results. Inspection interval
should be determined referring to the actual installation
environment or storage records.
3) If a valve is not used for a long time, the valve function
may be deteriorated when restarting operation, due toprecipitation or effusion of lubricant film. According to the
JIS standard, minimal operation frequency of a valve is
specified as once in 30 days. Before reaching that date
perform periodical test operation or take other measuresfor preventing the valve deterioration.
3.3 Residual energy
Maintenance requiring actual operation of a system shouldbe performed after pneumatic/electric shut-down andexhaustion of all residual electrical charge and compressed
air from the system. Make sure the movable components
do not move during the maintenance, and mechanically
fix them if necessary for safety. Care should also be taken
for components that may drop out during the maintenance
operation and components with sharp edges to ensure safety.
3.4 Communication
If multiple persons are involved in the maintenance operation,
keep all the personnel informed about the conditions including
power-off, completion of residual pressure exhaustion, poweron, and resumption of air supply.

④ Solenoid valve installation site

Use of a valve at the following sites requires compliances withspecial functional specifications and regulations. Consult oursales personnel in the planning process for anything unclear.
thing unclear.
1) Operating conditions not within the specified range
2) Significant risk for users, properties, or environment isanticipated
Eg: Use in explosive environment 3), use for nuclear power
plants, vehicles, medical components, components related
to the Occupational Health and Safety Law and/or theHigh Pressure Gas Safety Law, etc.
Note3）: Select Konan explosion-proof solenoid valves for use
in general gas explosive environment.

Solenoid Valves for Fluid Control and Valve Systems

General Handling Instructions and Precautions

Users Instructions
Followings are comprehensive precautions for operation of a solenoid valve and a system
incorporating a valve. Make sure to keep in mind these matters for maintaining safety.

Caution ① Transport of solenoid valves

1.1 Weight
For safety of operators, heavy-weight valves and valve units
should be transported with the aid of conveyer equipment.
Valve weight can be confirmed by referring to Konan
Pneumatic Solenoid Valve Catalogue and product drawings.
Mini-size valves should be handled with care, as they may
collapse by excessive force. Especially make sure not to holdthe lead wire when transporting the valves.
1.2 Dropping
During lifting or horizontal transportation of a valve, handle thevalve carefully not to drop or damage.
1.3 Dust prevention
Plastic plug is attached to the valve connection ports toprevent dusts and rusts from entering the valve. Do notremove the plug until immediately before piping. If the plug islost, take a protection measure with alternative cover.

Caution ② Storage

2.1 Storage during transport
If a valve is to be installed where it is exposed to wind andrain or other adverse environment, transport the valve to thespecified site just before installation. If the valve is to be stored
at the installation site by necessity, keep it packed and protectwith a sheet cover.
2.2 Storage
A valve should be stored as follows to prevent contaminationand material deterioration.
1) Avoid high temperature and humidity as well as places withdusts.
2) If a valve is to be stored for more than 1 year, keep it
packed or provide equivalent protection.
3) Long-term storage may result in sticking of packings orother components due to shortage of lubrication. In suchcases, conduct pre-conditioning operation of the valve
before regular use.
4) After a long period of storage, permanent deformation,change of size, or deterioration of packings and othercomponents would be a concern. After such storage period,
conduct a valve operation test. If any abnormalities arefound, perform an overhaul or exchange deformed/
deteriorated components as appropriate

Warning ③ Surrounding environment

3.1 Vibration/shock
1) Install a valve using hose connection to avoid the place
where the valve is exposed to excessive shock or vibration.
Care should be taken not to make outlet piping longer,
which may affect system response.
2) If a valve is to be installed in a place where it is exposed toexcessive shock or vibration, set the valve with a vibration
isolation table. Ensure the valve is firmly fixed at the setting
and connection portions fastened tightly. After start ofoperation, inspect the connections in a periodical manner
to check any loose parts or deformation and re-fasten
screws.
3.2 Handling during installation
For safety of operators

5

Do not ride on a valve and pipes or hang wires on theoperational equipment during installation.
3.3 Surrounding environment
Environment surrounding a valve should be considered
carefully. Avoid places where the valve is exposed to rain
and wind, direct sunlight, salt, corrosive gas, chemical fluids,organic solvents, steam, etc. Corrosion resistance measurecan be taken depending on the environment. Feel free tocontact our sales personnel for details.
3.4 Working temperature
Use a valve with specified range of ambient temperature andfluid temperature. Care should be taken especially for thefollowing cases.
1) Temperature of compressed air around an air compressor
may become high, which may cause deterioration of
packings or malfunction of the valve.
2) Coil life depends on thermal degradation of insulationmaterial. Avoid high temperature environment or continuous
energization as much as possible.
3) In a place where temperature is close to 0℃, remove
moisture in the compressed air with an air dryer. If thedehumidification is not performed, significant amount ofmoisture may freeze inside the valve to cause malfunction.

Warning ④ Modification

Do not modify a solenoid valve. Unexpected risk may arise.

Caution ⑤ Intermediate stop of a cylinder by control of a solenoid valve

1) A pneumatic cylinder can be stopped intermediately bycontrolling with a 3-position closed-center type solenoid
valve. Due to compressible nature of air, however, precise
stop position or retention rigidness of the stop position
cannot be secured.
2) If the piping area between the speed control valve and theclosed-center solenoid valve is large, air shifts from inside
the cylinder to the valve pipings even after the valve isclosed, thus the stop position shifts. In order to avoid this,install a speed control valve in front of the closed-center
valve to minimize piping length.
3) As sealing portions inside a valve or cylinder system allow
minimal leakage, it is difficult to maintain the intermediatestop position for a long time. If long-term retention of thestop position is necessary, install mechanical retention
equipment such as brake, lock, or latching system.

Caution ⑥ Spray lubrication using a lubricator

See Konan Solenoid Valve Catalogue if a valve needs lubrication.
For valves that need lubrication,set a lubricator at the inletof the valve and perform spray lubrication.
6.1 Type of lubricating oil
1) Use JIS K 2213 (ISO VG32 or VG46)type turbine oil for
lubrication using a lubricator.
2) Spray volume of a lubricator is determined by the numberof oil drops(typically 0.03cm3 per drop or 1.5 to 2.5 drops
per 1m3 of air).
6.2 Centralized lubrication
In principle 1 lubricator should be used for 1 valve. Lubricating
multiple valves may result in uneven oil supply to each valve or
actuator,particularly if there are differences in the operation

General Handling Precautions
frequency,pipe length,size,and installation height of theactuators. By grouping the valves and actuators with similar
conditions,centralized lubrication can be achieved.
6.3 Selection of oilless solenoid valve
For control of an oilless actuator,select an oilless solenoid
valve. If the valve is not frequently used,lubricated oil may
not reach the valve or actuator due to little spray volume.
1) Use specified grease for overhaul of an oilless solenoid
valve. Reconfirm the type of grease with our sales personnel.
2) A greased oilless valve or oilless actuator can be lubricated,but once lubricated,the grease will be exhausted.Althoughdurability is enhanced after the lubrication,continual lubrication
will be required.

Reference ⑦ Pneumatic system control

7.1 Sequence control
Follow the below steps for sequence control of an actuator
incorporating a pneumatic valve.
1) Detect the position.
2) Interlock the circuit of the valve that controls other actuatorsin the system.
7.2 Power failure and pneumatic pressure failure1) In case of power failure or emergency stop during asequence operation, select normal stop position of thevalve so that the cylinder at operation stops or shifts toa safe position. Depending on the type of valve following
action may be seen at emergency stop.
a) Single-acting return type: Shifts to the start position.
b) Double-acting detent (retention) type: Shifts to the final
stop position.
c) Closed-center type: Stops at the current position.
2) If operation is stopped in the middle of sequence andrestarting operation from the stopped position may cause
any trouble, manually control each actuator to return to thestart position. Indicate procedure to recover operation.
3) If operation is stopped in the middle of sequence and air
inside the system exhausted, a cylinder piston may drop
due to gravity or it may rapidly shift at the next air supply todamage operator or surrounding equipment. Make sure to
return the piston to the start position before exhausting air
from the system.
4) In order to complete a cycle operation even in case ofpressure failure, reserve sufficient amount of pneumaticpressure in an air tank.

Warning ⑧ Residual pressure exhaustion

In a system circuit using a check valve (non-return valve),a pilot check valve, and/or a closed center solenoid valve,
exhaust residual pressure separately or indicate warnings forresidual pressure, as air may be contained even the system is
not in operation.
Indicate the manual type valve for residual pressure
exhaustion in the system circuit drawing.

Reference ⑨ Circuit and piping

9.1 Pressure drop
In a pneumatic control system employing long pipes at theend or entrance of the system, sufficient pressure may not
be supplied due to pressure drop. Piping thus should bedesigned properly, or supplementary air tank should beinstalled to secure supply pressure if a valve is operated
intermittently.
9.2 Air filtration
Air supplied to a valve should be filtrated by a filter withnominal filtration rating of no more than 40 mm to remove
solid contaminants. Exhaust liquid drain or oil through thefilter or drain separator after sufficient cooling of the air.

Exposure to contaminated, high temperature compressed air
may deteriorate packings or other components, making thevalve life shorter.
9.3 Piping
1) Use galvanized pipe for steel tube piping and remove dusts
after screwing.
2) Before connection, clean the pipes by air flushing or
washing to remove internal dusts, moisture, and oil.
3) If a seal tape is used for screwing, wrap the tape around
twice or three times in a direction opposite to the screwing
direction, leaving 1.5 to 2 threads from the screw edge.
4) When screwing pipes and joints into a valve, use anappropriate size of wrench and fasten the pipes and joints
to the extent not causing air leakage. Forceful screwing
may result in cracking of the valve connection port orleakage/malfunction due to contamination with fragments ofsealing materials.
5) In case of 6A to 25A (Rc1/8 to 1) size pipes or joints, 4 to
5 threads should be screwed. An exercise for seal tapewrapping and screwing before actual work is recommended.
6) A valve (especially large-size valve) should be fixed not
only with the piping but also with supporting components.
For some mini-size solenoid valves with steel tube piping,supporting components may be used for the piping portion.
In this case sufficiently support around the valve with piping
clamp and other components.

Caution ⑩ Electrical circuit and piping

1) Reconfirm that the voltage and current (AC or DC) of powersource and the valve to be used are identical.
2) For DC solenoid, check the polarity of the connection
terminal to avoid improper connection.
3) For a double solenoid valve with common terminal, makesure not to perform improper common connection.
4) If TRIAC is used for the AC output of the PLC (sequencer),leakage current at power shut down may affect action ofsolenoid or indicator lamp. In such case submit the PLC
output specification to the PLC manufacturer or Konan
sales personnel to discuss about a method to decreaseleakage current.
5) Power surge due to electromagnetic induction at solenoid
power off may significantly shorten the operating life ofjunction on the electrical circuit. For Konan solenoid valves
without surge absorber, consult our sales personnel for amethod to connect surge absorber.
6) For lead wire connection, wiring should be conducted using
appropriate connecting terminal while keeping the wireloose.

Caution ⑪ Special valves

For valves with special specifications like below, consult oursales personnel before ordering regarding the conditions foruse.
1) Use with carbon gas or nitrogen gas
2) Use under conditions with high/low temperature or highradiant heat3) Use at a place with ozone or salt4) Use in explosive environment

Warning ⑫ Disposal

1) Do not incinerate a valve for disposal. It may explode oremit poisonous gas.
2) Check the material of each component of a valve withcatalogue or operation manual for segregation disposal.
Konan solenoid valves do not include materials indisposable
as general industrial waste.

Type
■ 3-port solenoid valve

3-port solenoid valve has 3 ports: fluid inlet (P-port), outlet (A-port),
and exhaust port (R-port). This is mainly used for operation of
single-acting actuators or diaphragm valves.
The valve structure is as follows:
Normally closed : Air flow stops when solenoid isde-energized.
Normally open : Air flows when solenoid isde-energized.

■ 5-port solenoid valve

5-port solenoid valve has 5 ports: a fluid inlet (P-port), 2 load
connection ports (A- and B-ports), and 2 exhaust ports (R1- andR2-ports).
This valve is mainly used for operation of double-acting actuators.
Two types (return, hold) are available, and three positioning (closed
center, exhaust center, pressure center) can be selected.
The exhaust port can be used as connection to flow control valve(exhaust valve).

■ Air-operated valve

This valve controls direction of air flow using air pressure signals,
unlike solenoid valves that utilize solenoid. The valve performanceis comparable to that of solenoid valves, except slightly longer
response time.

［Eg.］
When valve inlet pressure is 0.6 MPa andoutlet pressure 0.35 MPa, the flow rate of
the valve with effective cross sectional
area 20 ㎟ is calculated as follows:
75L/min (ANR) × 20 ㎟ = 1500L/min (ANR)

Flow rate in standard conditions per 1㎟
of effective cross sectional area L/min（ANR）◇ Flow Rate Calculation● P H =（1 〜 1.89）P L（In the case of subsonic flow）：● P H = ＞ 1.89P L（In the case of acoustic velocity flow）：
Q ： Flow［L/min（ANR）］
S ： Effective sectional area［mm2 ］
P H ： Valve inlet absolute pressure［MPa,abs］=〔Gauge pressure PH' +0.101〕［MPa］
P L ： Valve outlet absolute pressure［MPa,abs］=〔Gauge pressure PL' +0.101〕［MPa］
T ： Valve inlet absolute temperrature［K］
