as to occlude exhaust galleries. Perfect spacer
When fixed between a valve with built in double check valves and sub-
plate the perfect spacer can hold an actuator in a desired position any-
where along it's stroke for a considerable period of time.
Environment
When valve is mounted in a control panel or is energised for long
periods of time, make sure the ambient temperature is within the
specified range.
When used in temperatures higher than 60° please contact SMC.
How to use insert plug (Fig 9, 10)
When removing insert plug 1from manifold base,push the lever area
2of insert plug downward with thumb and pull it together with the
lead wire 3out.
When plugging the insert plug 1into the manifold base, push the
lever area of insert plug with thumb and plug it in its place in the
receptacle housing 4horizontally.
After plugging, pull lead wire out a little bit to ensure that insert plug
is secure.

stations +COM and enables you to rationalise the wiring process.
•No polarity.
Leakage voltage (Fig 12)
Note that when using a C-R device (surge voltage suppressor) for
contact protection, the voltage leakage may increase due to the
current leakage flowing through the C-R device.
Suppress residual voltage leakage as follows:
DC Coil 3% or less of rated voltage
AC Coil 20% or less of rated voltage
Lubrication
These valves have been lubricated for life during manufacture and as
such require no further lubrication.
CAUTION
However, if a lubricant is to be used with a rubber seal type, a turbine
oil type #1, (ISOVG32) should be used, continuous lubrication must be
carried out as the original lubricant will be washed away.
Manual override operation (Fig 13)
WARNING
Exercise EXTREME CAUTION when operating a solenoid manual
override as connected equipment will commence operation.
Ensure all safety measures are in place.
Non-locking push type (Fig 13, 13a)
1. Push down the manual override button (Orange), until it stops,
using a small-bladed screwdriver.
2. Hold this position for the duration of the check (ON position)
3. Release the button and the override will re-set to the OFF
position.
Slotted locking type (Fig 13b)
To lock
1. Insert a small-bladed screwdriver into the slot.
2. Turn the override through 90° (ON position).
3. Remove screwdriver
WARNING
In this position the manual override is in the locked 'ON' position.
To unlock
1. Insert small-bladed screwdriver into the slot of the manual
override.
2. Turn the screwdriver 90° in the reverse direction.
3. Remove the screwdriver, the manual override will re-set to the
'OFF' position.
Maintenance
WARNING
Ensure air and electrical supplies are isolated before commencing any
maintenance work.
1. The ingress of carbon and oil present in the air supply (mostly
from the compressor) into the valve can sometimes lead to
increased resistance between the spool and sleeve. In the worst
case it can lead to the spool adhering to the sleeve.Therefore it is
important to check the quality of the air often.
In order to minimise the risk of the above, it is recommended that
a Mist Separator (Series AM) is installed upstream of the valve
after a Standard Filter (Series AF).Also selecting a compressor oil
with minimal oxidisation characteristics would elevate any such
problems.
2. Should the valve and sleeve adhere to each other then disassem-
ble the valve and clean the assembly in a solvent based chemical
taking care not to contaminate any O-rings with cleaning agent.
Mounting
When disassembling and reassembling ensure that all components are
in their proper positions. Prevent gaskets from moving and torque
screws down equally.

Single solenoid operated valves may be mounted in any attitude. However,
in environments that subject the valves to vibration double solenoid oper-
ated valves should be aligned perpendicular to the vibration.
Never use in conditions where vibrations exceed 5G.
How to remove/replace base mounted type
1. Loosen 3 set screws (hexagonal socket head cap screws M3x31)
and pull solenoid valve out vertically. Failing to do so may result
in damage to the solenoid valve.
2. When mounting solenoid valve on to the base, engage plug
(underside of valve) and socket (top face of base) before replac-
ing and tightening screws.
Accessories
Individual supply spacer
An individual supply spacer complete with gasket may be fixed
between valve and subplate so as to provide an individual pressure
supply to any valve.
Individual exhaust spacer
An individual exhaust spacer complete with gasket may be fixed
between valve and subplate so as to provide an individual exhaust for
any valve.
Exhaust block disk
If valve exhaust affects the function of other valves on the manifold
then an exhaust block disks may be fitted between the sub plates so
as to occlude exhaust galleries.
