Air Supply
1. Type of fluids
The operating fluids must be compressed air. Contact
SMC when using the product with other fluids.
2. Large amount of drainage
Do not use compressed air containing a lot of condensate,
which can cause the operating failure of pneumatic
equipment. Install an air dryer or drain catch before the
filter.
3. Draining control
If an air filter is not drained, condensate will leak to the
secondary side and cause the operation failure of
pneumatic equipment. When it is difficult to control
drainage, the use of a filter with an auto drain is
recommended.
For the details of compressed air mentioned above, refer to
SMC catalog "Compressed Air Purification System".
4. Use clean air
Do not use compressed air which contains chemicals,
synthetic oils containing organic solvents, salts or
corrosive gases, etc., as this can cause damage or
malfunction.
1. If ultra dry air is used as a fluid, it can
deteriorate the lubrication characteristics of
equipment and affect the reliability (life) of
equipment. Contact SMC beforehand.
2. Install air filters.
Install air filters close to valves at their upstream side. A
filtration degree of 5
μｍ
or less should be selected.
3. Install an aftercooler, air dryer, or drain catch
before the filter and take appropriate measures.
Air that includes excessive drainage may cause
malfunction of valves and other pneumatic equipment. To
prevent this, install an air dryer, aftercooler or drain catch,
etc.
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 valves and
cause malfunction.
For the details of compressed air mentioned above, refer to
SMC catalog "Compressed Air Purification System".
Operating Environment
1. Do not use in atmospheres where the valve is in
direct contact with corrosive gases, chemicals,
salt water,
water or steam.
2. Products with IP67 (based on IEC60529) are
protected against dust and water, however, these
products cannot be used in water.
3. Products compliant to IP67 satisfy the
specification by mounting each product properly.
Be sure to read the Precautions for each
product.
4. Do not use in an explosive atmosphere.
5. Do not use in a place subject to heavy vibrations
or shocks.
6. The valve should not be exposed to prolonged
sunlight. Use a protective cover.
7. Remove the emissive heat when there is a
source of heat around there.
8. If it is used in an atmosphere where there is
possible contact with water droplets, oil, weld
spatter, etc., take suitable preventive measures.
9. When the solenoid valve is mounted in a control
panel or its energized for a long time, make sure
ambient temperatures is within the valve
specification range.
Maintenance
1. Maintenance should be performed according to
the procedure indicated in the Operation Manual.
Improper handling can cause an injury and damage and
malfunction of equipment and machinery.
2. Removal of equipment and supply / exhaust of
compressed air.
When equipment is serviced, first confirm that measures
are in place to prevent dropping of workpieces and
run-away of equipment, etc. Then cut the supply pressure
and power, and exhaust all compressed air from the system
using its residual pressure release function.
In the case of 3 position closed center type, exhaust the
residual pressure between valve and cylinder.
When the equipment is to be started again after remounting
or replacement, first confirm that measures are in place to
prevent lurching of actuators, etc., and then confirm that the
equipment is operating normally.
