Polarity
When connecting power to a DC specification solenoid valve
equipped with (indicator light) surge voltage suppressor, confirm
whether or not there is polarity. If there is polarity, take note of the
following points.
Without built-in diode to protect polarity,:
If a mistake is made, regarding polarity, the diode in the valve, the
control device switching element or power supply equipment, etc.,
may burn out.
With diode to protect polarity:
If a mistake is made regarding polarity, it will not be possible to
switch the valve.
② ② ② ②
Applied voltage
When electric power is connected to a solenoid valve, be
careful to apply the proper voltage. Improper voltage may cause
malfunction or burn out the coil.
③ ③ ③ ③
Confirm the connections.
After completing the wiring, confirm that the connections are
correct.
Lubrication
Caution Caution Caution Caution
① ① ① ①
Lubrication
1)
The valve has been lubricated for life at the factory, and does not
require any further lubrication.
2)In the event that it is lubricated, use class 1 turbine oil (without
additives), ISO VG32.
However, once lubrication is applied it must be continued, as loss
of the original lubricant may lead to malfunction.
Contact SMC regarding class 2 turbine oil (with additives), ISO
VG32.

Screwing in
When connecting fittings to valves, tighten as indicated below.
1) M3, M5 types
1. When using SMC fitting, follow the guidelines below. After
tightening by hand, tighten an additional 1/4 (M3), 1/6 (M5) turn
with a tightening tool. However, if miniature fittings are used,
tighten an additional 1/4 turn with a tightening tool after
tightening by hand. For fittings with gaskets with gaskets in 2
locations, e.g., universal elbow or universal tee, tighten an
additional 1/2 turn.
Note) If fittings are over-tightened, air leakage may result due to
breaking of fitting threads or deformation of the gaskets.
However, if fittings are not tightened sufficiently, loosening of
the threads and air leakage and may occur.
2. When fittings other than SMC fittings are used, follow the
instructions of the respective fitting manufacturer.
2) For threads
Fasten with the proper tightening torques as shown below.
