Sspunding Valve | Adjustable PRV - Scaled (Up to 3BBL)

Introducing Ss Brewtech's 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.

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.

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. 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 any time during operation.
