Dial in the fermentation pressure on your Ss Unitank with the Sspunding Valve! Unlike the PRV that comes standard on the Unitank, the Sspunding valve is adjustable. This ensures that the internal pressure during fermentation won't build up and exceed your desired pressure. The scaled Sspunding valve includes an etched sleeve with a scale between 0-2 BAR, allowing the brewer to dial in the pressure on the fly and without needing to reference the Unitank's pressure gauge.

The polycarbonate cup is designed to hold sanitizer so that the tank remains 100% sanitary throughout the course of the fermentation process.

With a 1.5" tri-clamp tee (17470) and 90-degree elbow (17471), the spunding valve can be installed on the Unitank’s blow off arm, as shown in the photo.

  • 304 Stainless
  • Only for use with pressure rated Unitanks

For Your 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.
