Introducing our new line of adjustable pressure relief valves, commonly referred to as spunding valves.  These valves enable Unitank fermenters to both ferment under pressure and condition beer before transferring to a keg.

Non-Scaled Spunding Valve | up to 2 bbl

The compact non-scaled version is perfect for a homebrewer that doesn’t mind taking the extra minute or two to dial in their valve's release pressure using the gauge included with their Unitank.
The kits are designed to hook up the Sspunding Valve to the Unitank blow off cane as shown. Kits include the following:

  • Sspunding Valve
  • Micro Tee
  • Micro 90° Elbow
  • 3x 1.5" TC Clamps
  • 3x 1.5" TC Gaskets

The polycarbonate cup is designed to hold sanitizer so that the tank remains 100% sanitary throughout the course of the fermentation process. 

Lastly, a final note on safety, always leave the fixed-pressure PRV included with the Unitank in place, never exceed the maximum rated working pressure of the vessel at anytime during operation.

Sspunding Valve Featuers

  • All 304 Stainless Construction
  • Only for use with pressure rated Unitanks
  • 1.5" TC interface
  • Removable sanitizer cup
  • Easy disassembly for cleaning

Note: Not for use on low-pressure vessels (Chronicals, etc.)

Spunding Valve Use and Operation

The Sspunding valve operation and installation is very simple. Make sure your o-ring and cup are fully inserted over the valve.

Fill the cup half full with diluted down sanitizer similar to what you would use in a spray bottle. Twist the valve to the appropriate BAR rating (this all depends on the processes for spunding).

If you are fermenting under pressure you would close and set after transfer a PSI or bar to your yeasts range (5 to 9 psi .3-.6 bar is common) and run this through the whole fermentation process. Just keep in mind, differences and variants will occur when fermenting under pressure so choose a strand that fits your profile.

To naturally carbonate, I would wait to close up until the last few points of your attenuation point and set it to around the 10 - 13 psi or .7 - .9 bar. The Sspunding valve can be set to a higher pressure than your PRV during the initial few days fermentation so that the discarded krausen comes out through the blowoff tube instead of the Sspunding valve. This will effectively keep the valve shut and clean until fermentation has become less messy.

For safety, always leave the fixed-pressure PRV included with the vessel in place, never exceed the maximum rated working pressure of the vessel at any time during operation.
