Where to put pressure switch?

[MudRunnerTD]

Electrically speaking install the pressure switch in the small red wire in-between the switch and the relay.

But... I have to ask why, unless you have installed an air tank.

I have a pressure switch in my system without a tank because the manifold and the the hoses to the quick connects all hold air. All my connectors don't allow free flow so only allow flow when something is plugged in so the system pressurizes.

Thats what i could not figure out... no tank for the switch anyway?

Mine is wired as Rodney has said...

The diagram is how it is now, not what I intend on doing. I'd like to in time to put a tank underneath.

Hey MudRunner, what non return valve did you use and was it Npt or bsp? Thanks

I'll take a pic and post it up for you in the next day or so mate.

Darren, I wasn't having a go at you at all mate.

How you use your vehicle(s) is totally different to how most people on here use them.

The OP hasn't stated that he wants to run lockers or an air tank so I asked the question.

Nah all good Rodney, no offense at all was taken mate. No dramas bud.

You could fit this into the system Im not sure those other Fuel NRV would hold and pressure

@ MR I take it all your air fittings terminate with Female Nitto style fittings.
OOI why do you want to pressurize such a small system, thinking your
compressor is hard mounted somewhere and maybe a line going to some lockers
and an outlet maybe front and rear. Think I just answered it myself lol Doh

@ Skts why do you want to hold pressure???

These are the Air Check Valves that I use... $2 bucks each http://www.ebay.com.au/itm/271455693...%3AMEBIDX%3AIT
These are the Pressure Relief valves I use... $2.50 each http://www.ebay.com.au/itm/391265177...%3AMEBIDX%3AIT
These are the gauges I use... $12 each http://www.ebay.com.au/itm/351546917...%3AMEBIDX%3AIT

I use that style Check Valve in line with Push In fittings of approp size.
The Pressure Relief blow off value depends on the system pressure so you select one as appropriate.
I try and have a gauge where it is easily visible, not required if the setup already has one and you can see it.

Don't forget to bleed off any pressure when you finish up.
Without a check valve many systems will slowly leak down when they are off so no biggee
Once you introduce check valves you introduce the possibility of trapping high pressure air in lines and if you get high thermal expansion you risk blowing a fitting or bursting a line.

Cheers mate. I would like a tank underneath and just want to install the compressor the one time to suit. I also want two outlets as well as having the trigger style tyre inflators that don't constantly flow.

Cheers for all that mate. Thank you.
