measured at 30˚C. Can be improved by controlling the applied current (e.x. PWM,
a spike & hold circuit, etc.). Please contact us for details.

Cautions concerning Power Supply

Power Source

1. Power supply by a constant current circuit is
recommended.
2. Operation by 12 VDC power supply or batteries is also

possible, but a resistor must be inserted between the
valve and the power source. See diagram on right.
