Blackwoods have a large selection, good quality, fairly pricey.I would like to know if there are 12V DC solenoid valves suitable for garden
sprinkler systems or is there only the 24V AC ones that I've seen at the
hardware? If there is such a solenoid where can I get them from?
Check out washing machine and dish washer spare parts. Quite cheap.I would like to know if there are 12V DC solenoid valves suitable for garden

You can get 12V valves but they draw about 1A and run very hot. They are
not rated for continuous use being labeled on the underside of the coil
for 4-min on 10-min off or something like that.
The 220V-240V AC types run cool and can be left on for long periods.
I can't remember if I tried the 24V AC ones. We started with 12V DC and
settled on 230V AC.

RS Components have one for approx $ 40.00 which is designed for
24Vac/12Vdc
draws approx 700mA, and if to be activated for periods longer than 5-10
minutes have water running through it as part of the continuous flow
cooling
system.
The part # is 342-023, this is the one I used in the Nuts and Volt
project.
You may even be able to use the 24Vac ones from Bunnings and the like on
12Vdc.

Well isn't this fun.
Most of them are used inside appliances likeAgreed, electrical safety is important. It's
probably best not to set fire to anything either.
So to keep Mr Speed happy; unless you're building a
commercial product stick with 24V solenoids, because
240V is too dangerous and 12V draws too much current.
The 240V solenoids must be used correctly to ensure maximum safety.
Can you tell us why there are 240V solenoids available?
Or you could actually have the sense to realise that whenYou could argue that to be absolutely safe
there should be no mention of anything that
could the slightest bit dangerous in this group.
You clearly did just that and are now desperatelyTo be of much use the group needs input and discussion from all angles.
I should have put a warning with my original comments but I was not
intending to recommend the use of high voltage solenoids at the time.
Just the usual mindless gutless silly stuff when the author hadInterresting comments a few months back in the Silicon Chip editorial
about this newsgroups, did you read it and what did you think?
No thanks for your pathetic excuse for bullshit.Thanks for your experienced input.
