Maintenance
1. Perform maintenance and inspection according to
the procedures indicated in the operation manual.
If handled improperly, human injury and/or malfunction or
damage of machinery and equipment may occur.
2. Removal of equipment, and supply/exhaust of
compressed air
Before components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply air and electric power,
and exhaust all air pressure from the system using the residual
pressure release function.
For the 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
the lurching of actuators, etc. Then, confirm that the equipment
is operating normally.
In particular, when a 2-position double solenoid valve is used,
releasing residual pressure rapidly may cause the spool valve
to malfunction, depending on the piping conditions, or the
connected actuator to operate.
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, connected equipment
will be actuated.
Operate after safety is confirmed.
5.
If the volume of air leakage increases or the valve
does not operate normally, do not use the valve.
Perform periodic maintenance on the valve to
confirm the operating condition and check for any
air leakage.
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 additives), VG32. If other
lubricant oil is used, it may cause a malfunction. Please contact
SMC for information on the suggested class 2 turbine oil (with
additives), VG32.
3. Manual override operation
When switching a double solenoid valve via the manual override
operation, instantaneous operation may cause the malfunction
of the cylinder. It is recommended that the manual override be
held until the cylinder reaches the stroke end position.
