Type of Regulator for LP Liquid

[Twodose]

What type and size regulator should be used for the liquid side of a Low Pressure Foaming Tire Cleaner?

I have been using Generant ½” for years, but have been having problems with them lately and want to try something different.

Will the small Mini regulators with the ¼ “ ports provide enough flow for a 7 bay wash?
Can't find anything on parkers website showing the flow rates for there regulators.

Thanks

What sort of pump are you using it on?

With a Procon, I like to use a JE Adams 7075 - you'll need to cut about 1/4" off the spring to turn it down low enough, but I haven't found anything more accurate.

Using ARO 666053-333 1/2" diapragm pump. I know the odd's of 7 bays using the tire cleaner all at the same time are not very high, but would like to know if using a 1/4" mini regulator would provide enough gpm.

This pump is around 11gpm.

666053-3eb at Kleen-Rite.

By the way... I have been using ARO's for about 10 years now with no problems. I know they are expensive, about $390 for this one and close to $500 for a teflon. But if you hook them up right with a 3 way solenoid valve that bleeds off the air pressure they work great.

Have also used G&L pumps and they are also very good.

Why do you use a regulator on the liquid side at all? I use FloJet, which is still the same basic setup, and there's no issue with consistency in the bay with the normal up-and-down pressure from the twin diaphragm pump. The liquid pressure is controlled by the air inlet pressure to the pump. I did think about using a liquid regulator on the outlet to smooth it out, but it just seemed like overcomplicating something that's been working fine.

I've used Watts regulators inline on low-pressure systems in the past, usually on bladder tank systems, and they work and last well.

You could set it up that way, never though about doing it like that since i have always used regulators.
I thought ARO's had to have 80psi for them to work right.
Are you using this in a ss or automatic?

The watts regulator you speak of, is the the mini?

I'm not familiar with the ARO's, but maybe your setup is why they last and others have bad luck with them.

I'm using the FloJets on SS; four of the six pumps are original and six years old, the other two were santoprene on tire cleaner and wax and failed after two years; the vitons on those now are four years old. All are dead-headed with no controls except the solenoids to the bays.

The Watts regulators I used to use have the bell-shaped top and a screw for adjustment rather than the T-handle - I don't see them in the Kleen-Rite catalog.

MEP001.. Your air line is coming straight off your compressor to your flo-jet on your tire cleaner? What psi is your compressor set at? Can you do this for your foamy brush and pre-soak?

There's an individual air regulator for each pump so they can be adjusted to suit the application.
