A spunding valve is a great accessory to have when performing pressure transfers and is a must-have for fermenting under pressure. Designed by the MoreBeer! R&D team and made from stainless steel components for long-lasting quality. Our spunding valve features the Torpedo Keg gas-in disconnect and our specially designed adjustable stainless gas pressure relief valve (D1833L).

Pressure Fermentation
Pressure fermentation is becoming more and more popular at the homebrew level, but in order to do it safely and accurately, you need a way to release excess pressure. You'll pressurize your vessel to your desired psi, but once fermentation begins and those hungry, active yeast start creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when the pressure gets to high and close up again when it's back to your desired psi.

Pressure Transfers
Even if you don't have a pressurizable fermenter, you may have done pressure transfers from keg to keg during filtering or after fining. During pressure transfers, it's a good idea to have a bit of head pressure in the receiving keg, especially if you're transferring beer that is already carbonated. Having a spunding valve in place will allow you to consistently control the head pressure and give you more consistent results, without losing carbonation in the process.


Note: The very end of the pressure relief valve can be adjusted by unscrewing the knurled adjustment knob. If too tight and not adjustable by hand, wrap a towel around the adjustment knob and loosen with pliers. Then finger tighten or loosen to desired pressure.

Pretty solid spunding valve with one major flaw. The spring is not stainless so it rusts. This is a huge fail for an otherwise great product.
