RE: Controllable water valves

[steve.cooper@xxxxxxx]

Would this be the mail

"I have just turned on my irrigation system at home so I don't have to
do
the
watering - I hate it.

I have used 12 volt water valves from RS as they are 12 volt for safety
and
have a BSP thread which means I can mate them to other plumbing and
watering
kit. The RS number is 342-023 and they also do the mating copper bit
342-023. They cost 9.43 and about 1.45 respectively + VAT of course
(www.rswww.com).

I have 4 all lined up and connected to a single tap. I found that it is
best
to only turn on one at a time because of the water pressure. Mine are
linked
through to hoselock stuff so SWMBO can cope. I also plan to have manual
on/off switches on them working through HomeVision input ports.

To power them I have a 12 volt transformer and reed relays. I then use
the
relay outputs from HomeVision to trigger the relays. HV may be fine on
its
own but better safe than sorry.

They have only been operating for about two days but so far so good. I
have
even bought two more valves so I don't have to mix 'leaky hose'
watering
with the 'lots of little jets' variety. I found the pressure drop was
annoying. My garden is 100' long to give you an idea.

Like Mark my electronic skills aren't up to much either so if anyone
wants
to supply us both a little reed relay board with 4 relays, that would
be
great.  Or even a circuit board and list of parts would be a
start.

Can't remember the code at the moment but I use six from RS components.
They
take 12 volts and I switch them from HV via a homemade relay board and
Cat5.
Try looking back through the archives for irrigation etc. They are about
11
quid + vat. If you are interested I think I posted piccys on yahoo.
quick check and yes.....

These are the old ones and there are now 6 but laid out in the same
way.
