Ensure correct connection of the lead wires to (+) (positive) and
(-) (negative) indications on the connector. For non-polarity type the
lead wires can be connected to either one.

malfunction).
Lead wire
Solenoids whose lead wires have been pre-wired are red positive and
black negative.

Leakage voltage
Type 40 Type 41 Type 42 When a C-R device (surge voltage suppressor) is used for the
- Type 41R Type 42R protection of the switching device, be aware that leakage voltage will
be increased by passing this leakage through a C-R device.
Suppress residual leakage voltage as follows:
Base Base Base DC coil: 3% or less of rated voltage

Lubrication
The valve has been lubricated for life at manufacture and requires no
additional lubrication.
CAUTION
However, if a lubricant is to be used, a turbine oil type #1 (ISO VG32)
should be used. If a lubricant is used, continuous lubrication must be
carried out, as the original lubricant will be washed away.
Energisation time
The double solenoid valve must be energised for at least 0.05 seconds
to ensure proper operation.Low
Low temperature application
May be used down to -10° if the air is sufficiently free of moisture.
Please use an appropriate dryer to ensure dry air preventing the valve
from freezing.
Energising in a long run
For use of long run energising, its specifications should be consulted.
