Air Supply
1. If ultra dry air is used as a fluid, the lubrication
characteristics of the equipment will
deteriorate and this can affect the reliability
(life) of the product. Contact SMC beforehand,
if using ultra dry air.
2. Install an air filter.
Install an air filter upstream near the valve.
Select an air filter with a filtration size of 5
µ
m or smaller.
3. Install an aftercooler, air dryer or drain catch
before the filter and take appropriate
measures.
Compressed air that contains a large amount of
drainage can cause malfunction of pneumatic equipment
such as valves. Take measures to ensure air quality,
such as installing an aftercooler, air dryer, or water
separator.
4. If excessive carbon powder is generated,
eliminate it by installing mist separators on the
upstream side of valves.
If excessive carbon dust is generated by the compressor,
it may adhere to the inside of a valve and cause it to
malfunction.
For detailed information regarding the quality of the
compressed air described above, refer to SMC's "Air
Cleaning Systems".
Environment
1) Do not use in an environment where corrosive
gases, chemicals, sea water, water or steam are
present.
2) Do not use in an environment where flammable gas
or explosive gas exists. Usage may cause a fire or an
explosion. The product 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.
Maintenance and Inspection
(1) Maintenance should be performed according
to the procedure indicated in the Operation
Manual (this copy).
Improper handling can cause an injury; damage and/or
malfunction of equipment and machinery.
(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 its residual
pressure release function.
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
Valve should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air
supply.)
1. Draining
Remove drainage from air filters regularly.
2. Lubrication
Lubrication must be continued once it has been used in
the system.
Use class 1 turbine oil (with no additive), ISO
VG32.
If other lubricant oil is used, it may cause malfunction.
Please contact SMC for suggested class 2 turbine oil
(with additives), ISO VG32.
