The Sspunding Valve from Ss Brewtech allows you dial in the precise pressure at which you want your Unitank fermenting. A spunding valve is essentially an adjustable pressure relief valve. Normal PRVs that are found on kegs, couplers and come stock on Ss Unitanks, operate as safety features that will release pressure when it's nearing dangerous levels. Spunding valves, on the other hand, allow you to set the release pressure much lower. Simply dial in your desired fermentation pressure, and the Sspunding valve will release excess pressure when it gets too high.
The compact, non-scaled Sspunding valve will take a little extra time to set, but can be done easily enough using the gauge included on the Ss Unitank. Check out FE892B for the scaled version.
The polycarbonate cup is designed to hold sanitizer so that the tank remains 100% sanitary throughout the course of the fermentation process.
You can pair the spunding valve with a 1.5" tri-clamp tee (H666) and 90-degree elbow (H667), which enables the unit to be installed on the Unitank’s blow off arm, as shown in the photo. (Scaled version shown in example photo - FE892B).
Not for use on low pressure vessels (Chronicals, etc.)
