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.

Scaled | up to 3.5 bbl
The scaled version includes an etched sleeve with a scale between 0-2 BAR, along with a pressure calibrated spring. This version is perfect for a home or nano brewer that wants to be able to dial in pressures on the fly without having to match the release pressure using a gauge. The scaled version also features a pressure release knob to quickly and easily verify or equalize tank pressure.
Non-Scaled | 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.
- All 304 Stainless Construction
- Only for use with pressure rated Unitanks
- 1.5" TC interface
- Removable sanitizer cup
- Easy disassembly for cleaning
Not for use on low-pressure vessels (Chronicals, etc.)

Run small, size it up
Color: Mushroom, Size: 32W x 30L, Color: Mushroom, Size: 32W x 30L
They go small, Im 5'8", 165lbs, usually 32x30 fits just rigth in most brands Levis, Izod, whatever, can't even close the zipper on this one, my dingus prints in the front if I manage to close it, I will try a 34 or even 36, if you want one, size it up. Length is right.
Anyway, the pant is good, sturdy looking material, is not soft but nothing uncomfortable probably gets right after break it in, reinforced stitches on pockets. I think they would work great for a technician, salesman or an engineer, those jobs where you have to look like a human being with a polo shirt but sometimes needs to do something without ripping your pants while crouching or for daily abuse of the regular Joe, will try another that fits

Good, but size up!
Color: Black, Size: 30W x 29L
These are exactly what I wanted, but as many have stated, you need to size up. I found that going up two sizes (from my usual 28 to a 30) made for a great fit. I love that they come in a 29 length. One anything point is they came with creases in them from being folded in the package for a length of time. I had to steam and press them before wearing. I’ll likely buy them in other colors.
