Warning
Warning
Operating Environment
1.
Do not use in an atmosphere having 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.
5. Remove any sources of excessive heat.
6. If it used in an environment where there is possible contact
with oil, weld spatter, etc., exercise preventive measures.
7. When the solenoid valve is mounted in a control panel or its
energized for a long time, make sure ambient temperature is
within the specification of the valve.
8. Install silencer in EA/EB/Pilot EXH port to prevent dust from
entering in the dusty ambient.
1. Temperature of ambient environment
I
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 environme
●
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.
If handled improperly, malfunction and damage of machinery or
equipment may occur.
2.
Removal of equipment, and supply/exhaust of
compressed air
When components are removed, first confirm that measures are
in place to prevent workpieces from dropping, run-away equipment,
etc. Then, cut off the supply pressure and electric power, and
exhaust all compressed air from the system using the residual
pressure release function.
For 3-position closed center type, exhaust the residual pressure
between the valve and the cylinder.
When the equipment is operated after remounting or replacement,
first confirm that measures are in place to prevent 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 the manual override is operated, connected equipment will
be actuated. Operate 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 of the valve to
confirm the operating condition, and if there is
any air leakage.
1. Drain flushing
Remove drainage from the air filters regularly.
2. Lubrication
This solenoid valve requires lubrication, once lubrication has
been started, it must be continued.
Use class 1 turbine oil (with no additive), ISO VG32 because if
other lubricant oil is used, it may cause malfunction. Please
contact SMC for suggested class 2 turbine oil (with additive), ISO
VG32.
