Precautions for 5 Port Solenoid Valve 5
Be sure to read before handling.

Operating Environment

Warning
1. Do not use in an atmosphere having corrosive
gases, chemicals, sea water, water, water steam, or
where there is direct contact with any of these.
2. Products with IP65 and IP67 enclosures (based on
IEC60529) are protected against dust and water,
however, these products cannot be used in water.
3. Products compliant to IP65 and IP67 satisfy the
specifications through mounting. Be sure to read the
Precautions for each product.
4. Do not use in an environment where flammable gas
or explosive gas exists. Usage may cause a fire or
explosion. The products do not have an explosion
proof construction.
5. Do not use in a place subject to heavy vibration
and/or shock.
6. The valve should not be exposed to prolonged
sunlight. Use a protective cover.
7. Remove any sources of excessive heat.
8. If it is used in an environment where there is
possible contact with oil, weld spatter, etc., exercise
preventive measures.
9. When the valve is mounted in a control panel or its
energized for a long time, make sure ambient
temperatures is within the specification of the valve.

Maintenance

Warning
1. Perform maintenance inspection
according to the procedures indicated in
the operation manual.
If handled improperly, malfunction and damage of
machinery or equipment may occur.
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 the residual
pressure release function.
For 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 lurching of
actuators, etc. Then, confirm that the equipment is
operating normally.
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 operation
When the manual override is operated, connected
equipment will be actuated. Operate after safety is
confirmed.
Caution
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 additive), VG32
because if other lubricant oil is used, it may cause
malfunction. Please contact SMC for suggested
class 2 turbine oil (with additive), VG32.
