What pressure should the pressure relief valve be set at? everybody says the air tank should be set at 800 psi and the diagram says to set it at 750, but then the thing would be blowing off all the time, shouldn't it be set a little higher, something like 825 or something??

The correct setting is 50 atmospheres which is approximately 735 PSI at sea level.

The Russian setting of this device (out of the Sukhoi and Yak books I
have) is 50 atmosphere, which equates to about 735 PSI.

The Russian system is designed to work at no higher than that pressure.
Exceed it at your own risk.

If you have an EMERGENCY blow-off valve that is designed in as an EXTRA
safety measure on your Moose Henry, then it might be a good idea to set
it a little higher than 735 PSI, in which case 800 PSI on the emergency
bottle blow-off valve might be reasonable. However, the primary
pressure regulator/relief-valve (whatever you want to call it) should be
set to keep the overall system pressure from not exceeding 735 PSI.

Best Regards,

Mark

Thanks guys

Does anyone know where I can buy one that is already set at 50 atmospheres? And a Gauge that will fit in the dash?

Henry, the ones that the Yaks and CJ's use are adjustable. SUPPOSEDLY
they are set up from the factory to break at 50 atmos, and the ones Doug
Sapp sells are like that. However, even if you buy one new, it is going
to change over time, so you might as well get used to the idea of having
to adjust it. My opinion on the matter... And there is an alternative.
You can use ANY pressure relief valve that is set to release at 735 PSI
plus or minus a tad. I saw one on Sergei Boriak's old SU-31 that was
really slick. I remember looking it up by the part number, and tracing
it down to the people who made it. I wanted one for my own airplane!
That was until I saw that the price was about $800 for that stainless
steel jewel! So, I stayed with the cheaper stuff... But still...
They're out there and they are a lot better than what comes in the Yak's
and CJ's now. The one I saw was adjustable from 700-900 PSI and held a
setting to within 5 PSI, and had a pull release ring on it to bleed the
system down. Pretty cool. If you have the money, I would recommend
looking into something like that.

As for a gage... My input would be to just plumb everything with
standard AN fittings everywhere possible and stay away from, or convert
over from, metric. To that end, a standard pressure gage in PSI would
be just fine. Just look for something say from the 0-1000 psi range.

Guys,
I replaced my entire air system quite a while ago and have since
sold the plane. I used brand new stainless valves that were approx.
$120ea. They came with no spring. There was a spring selection chart
based on the pressure you want. I don't recall the details off-hand,
and I'm out of town. However, if anyone want's this info I can look
it up when I return home (I should have all the receipts).

Wes, could you possibly give me a reference on the relief valve you used? I
am VERY VERY interested! (BIG TIME) I really am tired of messing with the
Russian stuff.

Mark,
It looks like I gave all the paperwork to the buyer of my old plane.
However, using my marginal memory, I located the valve...

http://hylokusa.thomasnet.com/item/rv-series-relief-valves/relief-valve/pn-5069?&plpver=10&assetid=g1001

In case the link doesn't work, it's a Hy-Lok RV2MF-4N with the Yellow
spring. (It might have been the purple spring run all the way out.
I'll try to find out for sure.)

(Disclaimer) I would verify with the distributor the correct pressure
range etc... before ordering.

I used two of them on a Yak 55M and had great success.

Let me know if I can help with anything else.

Wes

Henry,

Are you using the original Russian relief valve? Kimball's setup? (which is a readily available Parker brand valve), another setup per the Moose community?

Don't mean to pry, but the Parker stuff allows for a different way of relief than the Russian stuff or the type of valve Wes has shown (which I think is pretty slick in itself).

Don't mean to bury you with extraneous data, but I've found some other options from some valve manufacturers (in stainless with your choice of standard pipe threaded inlet sizes and cfm ratings, 12 or 24V); a couple brands are Sejn and Noshok.

The operational mode of these valves could be for relief, unloading for the compressor, or a combination of both.

Mike,
Just an FYI. The valves I used were for emergency pressure relief
only. I also had an, "Unload" valve that I would open after the
pressure built back up after a start.

I think Doug Sapp of Omak, WA. has a great air system. I am extremely happy with it.
