Outer Limits 4x4 Board

I am planning on running two air tanks that will cut out at different pressures. One small one for lockers and the other for air tools, tyres and anything else. I am just giing to have two different pressure switchwes for the two tanks and have them control an air solenoid.

Is there anything out there readily available with 12V control that anyone can suggest?

Alternatively, am i going too far and will i be able to use one tank, and will the standard 90-130Psi switch be fine for lockers and air tools??

gas lockoff ????

Im a sparky not a plumber. i assume its a safety thing on gas appliance??

I would need a normally closed solenoid for fail safe so i dont lose all air if something goes wrong.

Run one tank at 130 ish psi and use a pressure regulator to regulate it down to 90psi for the manifold that the air locker solinoids are on.

I think his talking about a LPG lock off valve..

more info on this please as that would solve all problems!!

ok lpg lockoff it may do the job just worth looking at

GRA sell lockoffs...

Well you run your 130 psi pressure switch on your pump and this fills the tank to 130psi (you still with me )
You then get a pressure regulator like used when spray painting that has a big knob that you can turn to adjust the output pressure. Set this to aprox 90psi and run an air line to a manifold that your airlocker solinoids are screwed into.

It'll be fine and anything else you do will be a waste of time and money.

Micky since your a sparky(same here) get yourself a pressure switch from a pressure pump(water) or best of all go buy yourself one of those $100 compressors from supercrap and retro fit/wire all the gear over, damn you can even use the tank itself!


Thats what im going to be doing anyway

try here http://www.metalwork.it/eng/elettrovalvole.html we use heaps of 12/24v soleniods at work . not cheap though.

this is what regulators are designed for! they cost $40 and will give a pretty constant pressure regardless of tank pressure (as long as its above 90). Fit a one way valve if you are worries the main tank will go below 90 psi.

would a regulator mounted in a vehicle handle all the vibrations and such of driving around???

the solenoids you find on airhorns would probably work, they operate up to 150psi, are normally closed, and can be found on ebay (hornsales or something is a aus seller that had them at one stage)

If a regulator can handle the vibrations when it is strapped to a compressor I am sure it will handle the vibrations on a 4wd
