Lubrication

Warning
Lubrication
[Rubber seal]
1) The valve has been lubricated for life by the
factory and does not require any further.
2) If a lubricant is used in the system, use class 1
turbine oil (no additive), ISO VG32. For details
about lubricant manufacturers' brands, refer to the
SMC website. Once lubricant is utilized within the
system, since the original lubricant applied within
the product during manufacturing will be washed
away, please continue to supply lubrication to the
system. If turbine oil is used, refer to the Material
Safety Data Sheet (MSDS) of the oil.
[Metal seal]
1) These valves can be used without lubrication.
2) If a lubricant is used in the system, use class 1
turbine oil (no additives), ISO VG32. For details
about lubricant manufacturers' brands, refer to the
SMC website.
Note）If a lubricant is used in the system, use
class 1 turbine oil (no additives), ISO VG32. For
details about lubricant manufacturers' brands,
refer to the SMC website. Additionally, please
contact SMC for details about class 2 turbine oil
(with additives) ISO VG32.
Lubrication amount
If the lubrication amount is excessive, the oil may
accumulate inside the pilot valve, causing
malfunction or response delay. So, do not apply a
large amount of oil. When a large amount of oil
needs to be applied, use an external pilot type to put
the supply air on the pilot valve side in the non-lube
state. This prevents the accumulation of oil inside
the pilot valve.

Air Supply

Warning
1.
Type of fluids
Please consult with SMC when using the product in
applications other than compressed air.
2.
When there is a large amount of drainage.
Compressed air containing a large amount of
drainage can cause malfunction of pneumatic
equipment. An air dryer or water separator should
be installed upstream from filters.
3.
Drain flushing
If condensation in the drain bowl is not emptied on a
regular basis, the bowl will overflow and allow the
condensation to enter the compressed air lines. It
causes malfunction of pneumatic equipment. If the
drain bowl is difficult to check and remove,
installation of a drain bowl with an auto drain option
is recommended. For compressed air quality, refer
to SMC's Best Pneumatics catalog.
SY Series
Precautions for 5 Port Solenoid Valve 4
Be sure to read before handling.
4.
Use clean air
Do not use compressed air that contains chemicals,
synthetic oils including organic solvents, salt or
corrosive gasses, etc., as it can cause damage or
malfunction.
Caution
1. When extremely dry air is used as the fluid,
degradation of the lubrication properties in
side the equipment may occur, resulting in
reduced reliability (or reduced service life)
of the equipment. Please consult with
SMC.
2. Install an air filter.
Install an air filter upstream near the valve. Select
an air filter with a filtration size of 5 μm 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 dust 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.
