I've found these on Ebay and have an application that they would be better for than a straight on-off valve.

But has anyone used them and can anyone make head-or-tail of this electrical specification?

Hi Rob

Looks like it wants a short pulse of 3.6v @ 1/2 an amp to open it, and
then a short pulse of the opposite polarity to close it.... though
that's a bit 'unfriendly' from the point of view of the driver circuitry.
'Spose it could be done with 6v 'centre-tapped' (so 0v is half-way up
the battery stack, if using batteries)

Does that make any sense?

use an H bridge, then only 5V supply needed.

Electric resistance: 9 pulse width 30ms

So it wants 3.6v 500mA for 30ms, plus the other polarity for opposite action. 30ms seems remarkably short for a water valve solenoid, call me unconvinced about that bit. I'd expect more like 300ms.

I can't see the device or its spec.
Does it have separate connections for logic and power, or are
they one in the same?

Not so sure about the "beautiful" ...

Hi Rob,

I know this is an old post but did you ever get this working?
