Description 

This adjustable pressure relief valve has a sensitivity of 0 to 15 psi. It has a 1/4" female flare fitting on one end, which attaches to any threaded ball or pin lock gas fitting. Use this to make a keg pressure relief valve. Adjust the relief pressure by turning the knob on the right side of this assembly. Also known as a Spunding Valve.

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

Leaking
Bought two. Both leaked. 

William's Brewing Responds:  We shipped some of these without thread sealant between the ¼" flare and ¼" NPT fitting. We have corrected all of ours in stock thanks to you. We also appreciate sealing the two you received without proper thread sealant.

Multiple uses
I bought two of these and am very happy with them.  I use them for pressure fermentation, for properly carbonating my kegs, and for checking my keezer and kegs for those tiny CO2 leaks that dish soap or star-san can't find.  The screw adjustment mechanism is a bit crude for fine adjustment, but I can get within my target range when pressure fermenting.  The cost is very reasonable, as I built one previously and the parts cost as much as this pre-assembled one from Williams.

Great for Pressure fermentation!
Works very well for fermenting under pressure and controlling pressure for self carbonation. Easy to use and check keg pressure at any time.

Great Idea - can easily be improved
I bought one of these relief valves for natural carbonating etc.  It works great for measuring the pressure in the secondary before pushing to the serving tank.  However, I am not so sure it works as well to maintain a precise CO2 pressure for carbonation.  I think the product could be dramatically improved if the threading on the pressure relief valve was finer.  It is a very coarse thread that is difficult to dial in to the target pressure.

Does this device automatically release pressure or do you have to manually release
You adjust a spring tension valve to release pressure automatically.

I purchased this valve with a ball lock attachment to use it as a spunding valve. can this be used this way? my kegs seem to always lose their pressure.
This item is used for bleeding off excess pressure from your keg, so yes it can be used as a spunding valve. If you are loosing pressure beyond your set pressure you must have a leak. Check all joints with soapy water and make sure you use teflon tape on all threaded joints including the ball lock fitting threads.

Even if its clamped down all the way will this spunding valve still release pressure after 15 psi? or if the needle is clamped down will it completely close the valve and no pressure will be released?
If it is clamped down all the way, it will not release pressure until at least 30 PSI or so. However, you will damage the 0-15 PSI gauge on the valve as it will be forced into a higher range that it is designed to work after 15 PSI.
