Description
 
This spunding assembly includes everything you see in the photo (if you select Ball Lock in the dropdown)

Ball Lock or Pin Lock Gas QD or SANKE (select in drop down) Note that if you select SANKE, the input to the spunding will be a tailpiece and beer nut but it does NOT include a keg coupler.
FFL to NPT adapter
TEE
0-30 PSI Gauge
Adjustable PRV (Pressure Relief Valve) Modified for lower pressures

*note that we've modified the PRV to have a lighter spring in order to make the lower pressure adjustability more sensitive in the 0-30 PSI range. We don't know the exact maximum pressure it will hold, but it is at least 30 PSI. The PRV has pressure markings on it but the new spring re-calibrates the unit such that the markings are completely unreliable. Vent pressure must be set by watching the gauge.

Uses? Measuring carbonation level in a keg already carbonated (measure temp, measure constant pressure over an hour, refer to carbonation chart), Vent a keg that is naturally carbonating with priming sugar to avoid overcarbonation, pressure ferment in a corny (the true meaning of spunding).


We've had a lot of questions about how to use this device. First, please be aware that we don't have a lot of experience using spunding for pressure ferments but here are a few notes. You can use this device to check and/or vent a keg that has had the gas source disconnected. If you want to just use it to check pressure, turn the PRV all the way clockwise so that it doesn't vent and then connect to the keg's gas post. If the pressure is higher than you wanted, turn the PRV counterclockwise to allow venting.

In order to set the PRV pressure for venting during fermentation, it's best to pressurize the keg first to just over your desired vent pressure, rotate the PRV clockwise nearly all the way and then attach the spunding valve to the keg. Rotate the knob counter-clockwise slowly until it begins venting. Find the spot where it vents down to your desired pressure and then stops. To check that you've set it properly, remove the spunding, repressurize the keg to a few PSI above your set pressure and then reattach the spunding to watch for appropriate pressure venting.

This process sounds tedious but gets much easier after you've done it once or twice. You can also save gas by connecting the spunding directly to a gas source using our ball lock jumper post. If you don't have a CO2 source, it would be best to start using the spunding until after fermentation has become quite active.
That way it will be building pressure while you are working on adjusting the knob

Warning:We recommend using a corny keg with a lid mounted overpressure vent in ADDITION to using the spunding. It's always better to have redundant overpressure protection when fermenting in a pressure vessel. NOTE: the pressure scales on the adjustable vent are meaningless, ignore them. We have changed the stock 0-100psi spring out for one that is closer to 0-20psi. If you want it to hold a little more pressure, you can remove the spring, stretch it out so that it measures about 1.25” at rest and reinstall. We’ve also included the stock spring in a little zip lock bag should you wish to restore it to full 100psi capability (NOT RECOMMENDED)

Pressure ferment lagers now and believe me later December 8, 2017
Reviewer: John from Seattle, WA United States  
I saw a review wishing they were relabled for the lighter spring.  I have been using these end dial valves from an industrial source, and the original labels have no relation to actual pressure either.  They work well and I wish I would have seen them here first for the same price with the spring upgrade!   Brew Hardware kills it every time!

Carbonation totally dialed in! November 27, 2017
Reviewer: Mike Sharp from MOUNT DESERT, ME United States  
I had previously purchased a carbonation lid which has greatly reduced the amount of time it takes to carbonate a keg.   I still had mixed results with the carbonation.  The addition of the spunding valve has allowed me to dial in the carbonation perfectly!  I've used it four times and every keg has poured a perfect first pint!

Works Great! November 3, 2017
Reviewer: John Agee from Bakersfield, CA United States  
Happy with the spunding valve. I've been using it to pressure transfer finished beer.
I followed the instructions to dial in where 5psi is on the PRV and it's been working great.

Spunding Valve works October 22, 2017
Reviewer: Hugo Vanegas from Eglin AFB, FL United States  
Awesome product at a good price.  Everything works as advertised.  The only thing I would change would be an accurate label replacing the original one to reflect accurate PSI due to the custom spring.

great August 29, 2017
Reviewer: greg m from powhatan, VA United States  
Product was purchased from BH and arrived very quickly along with proper packaging. I would highly recommend you give BH a try for any of your brewing necessities.
