Introducing a 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

This 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 polycarbonate cup is designed to hold sanitiser so that the tank remains 100% sanitary throughout the course of the fermentation process.
You can pair the spunding valve with our micro tee and micro 90 degree elbow, which enables the unit to be installed on the Unitank’s blow off arm, as shown in the photo. 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.
