Solid product but needs instructions
The product works great, but it took me a while to figure out how it works since it didn't come with any instructions. It would be a 5 if it came with a 30 PSI gauge and instructions. 15 psi doesn't work for sours and wheat beers.

Just what I needed
I use this to regulate the carbonation in my kegs. It’s perfect for overcarbonated kegs.

I use it every week
This baby is the cat's meow.  Finished Lager in 7 days at 68F
I don't do anything to control temperature.
I use it with a gray ball lock (gas in) with flare fitting.
I oxygenate 2.75 gallons of wort by pouring it from 3 feet up into a 5 gallon ball lock keg (with 1 1/2" cut off the serving tube.  I add 1L yeast starter, close it up, and use CO2 tank to bring it up to 10PSI.  I burp it to get rid of the O2.  In 12 hours it is almost always up to 1BAR.  I fiddle with it until it is about 14PSI.  On day 5, I cold crash, and transfer under pressure to a serving keg.  My only complaint is that 1BAR is at the upper limit - I would prefer that 1BAR be in the "center" of the gauge.

Adjustable Pressure Relief Valve
I use this to do a closed pressure transfer from a unitank to a keg.  While this doesn't provide a very fine adjustment, it does get the job done of holding the pressure reasonably well at some set value.  Adjusting the set point is very easy, it just takes a few tries to get it exactly where you want it. You can probably build this for a few bucks less, but this is already assembled and pressure tested.  Money well spent.

Best design out there
These are by far the best quality spunding valves. Precise adjustments!

Can this relief valve be used as part of a low pressure air inflating system for the purpose of limiting the maximum pressure in the system while using a high pressure input device?
We can't recommend using this product for anything other beading off excess CO2 from a beer keg.

Can this be used in a water application?
No, this is designed for gas.

How do I zero out the guage?
Probably the easiest thing to do is replace the gauge.

I would like to use this to keep a constant pressure of say, 8 pounds, on my keg for dispensing. Would this do the trick? Thanks
Yes, you can set it to the desired pressure and it will release if the keg gets higher.
