VFR6000 Series
5 Port Solenoid Valve / Precautions 4
Be sure to read before handling.
Air Supply
Caution
1. When extremely dry air is used as a fluid,
degradation of the lubrication properties inside
the equipment may occur, resulting in reduced
reliability (or reduced service life) of the equip-
ment. Please consult with SMC.
2. Install an air filters.
Install an air filter upstream near the valve. Select an air
filter with a filtration size of 5µm or smaller.
3. Take measures to ensure air quality, such as by
installing an aftercooler, air dryer, or water
separator.
Compressed air that contains a large amount of drainage
can cause malfunction of pneumatic equipment such as
valves. Therefore, take appropriate measures to ensure
air quality, such as by providing an aftercooler, air dryer, or
water separator.
4. If excessive carbon powder is seen, install a
mist separator on the upstream side of the
valve.
If excessive carbon powder is generated by the
compressor, it may adhere to the inside of a valve and
cause it to malfunction.
For compressed air quality, refer to SMC's Best Pneumatics
catalog.

Operating Environment

Warning
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 is 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 temperatures is within the specification
of the valve.
Warning
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, equipment will be
actuated.
Operate after safety is confirmed.
Caution
1. Drain flushing
Remove drainage from the air filters regularly.
2. Lubrication
In the case of rubber seals, 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.
