DXT1215 Series
5-Port Solenoid Valves Precautions 3
Be sure to read this before handling products.

Wiring

1. The solenoid valve is an electrical product. For safety,
install an appropriate fuse and circuit breaker before
use.
1. Applied voltage
When electric power is connected to a solenoid valve, be careful
to apply the proper voltage. Improper voltage may cause
malfunction or coil damage.
2. Check the connections.
Check if the connections are correct after completing all wiring.
3. External force applied to the lead wire
If an excessive force is applied to the lead wire, this may cause
faulty wiring. Take appropriate measures so that a force of 30 N
or more is not applied to the lead wire.

Lubrication

1. Lubrication
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
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.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. Without continued lubrication, malfunctions could occur.
If turbine oil is used, refer to the Safety Data Sheet (SDS) of the
oil.
2. 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.
1. Type of fluids
Please consult with SMC when using the product in applications
other than compressed air.
When there is a large amount of drainage
2.
Compressed air containing a large amount of drainage can
cause the 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. This may cause the malfunction of
pneumatic equipment. If the drain bowl is difficult to check and
remove, the installation of a drain bowl with an auto drain option
is recommended.
For compressed air quality, refer to the SMC Best Pneumatics No. 6
catalog.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic
oils that include organic solvents, salt, corrosive gases, etc., as it
can cause damage or malfunction.
1. When extremely dry air is used as the fluid, degradation
of the lubrication properties inside 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 the 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 an excessive amount of carbon powder is present,
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 the SMC Best Pneumatics No. 6
catalog.
