Warning
Operating Environment
1. Do not use in an atmosphere containing corrosive
gases, chemicals, sea water, water, water steam, or
where there is direct contact with any of these.
2. Do not use in an environment where flammable
gas or explosive gas exists. Usage may cause a
fire or explosion. The products do not have an
explosion proof construction.
3. Do not use in a place subject to heavy vibration
and/or shock.
4. The valve should not be exposed to prolonged
sunlight. Use a protective cover.
Note that the valve is not for outdoor use.
5. Remove any sources of excessive heat.
6. If it is used in an environment where there is
possible contact with oil, weld spatter, et.,
exercise preventive measures.
7. When the solenoid valve is mounted in a
control panel or it’s energized for a long period
of time, make sure the ambient temperature is
within the specifications of the valve.
(1) Temperature of ambient environment
Use the valve within the range of the ambient temperature
specification of each valve. In addition, pay attention when
using the valve in environments where the temperature
changes drastically.
(2) Humidity of ambient environment
● When using the valve in environments with low humidity, take
measures to prevent static.
● If the humidity rises, take measures to prevent the adhesion of
water droplets on the valve.
Maintenance
1. Perform maintenance inspection according to
the procedures indicated in the operation
manual (this document).
If handled improperly, human injury and/or malfunction or
damage of machinery and equipment may occur.
2. Removal of equipment, and supply/exhaust of
compressed air
Before components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply air and electric power,
and exhaust all air pressure from the system using the residual
pressure release function.
When the equipment is operated after remounting or
replacement, first confirm that measures are in place to
prevent the lurching of actuators, etc. Then, confirm that the
equipment is operating normally.
3. Low-frequency operation
Valves should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air supply.)
4. Manual override
When a manual override is operated, connected equipment
will be actuated.
Operate only after safety is confirmed.
5. If the volume of air leakage increases or the
valve does not operate normally, do not use
the valve.
Perform periodic maintenance on the valve to
confirm the operating condition and check for
any air leakage.
1. Drain flushing
Remove drainage from the air filters regularly.
2. Lubrication
Once lubrication has been started, it must be continued.
Use class 1 turbine oil (with no additives), VG32. If other
lubricant oil is used, it may cause a malfunction.
