Spunding Valve Tips, Tricks & Troubleshooting

spunding valve tips

A Spunding Valve allows you to maintain a set pressure. If pressure in the vessel exceeds the set point, it is expelled. It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.

Why a Spunding Valve?

There are loads of homebrew related applications for a Spunding valve ranging from pressurized ferementation to naturally carbonating to fixing over carbonated beers and lots more.  Check out our resource post on the subject.  It’s arguably the go-to resource on the Internet on the subject

Spunding Valve Tips, Tricks & Troubleshooting

  1. Check for leaks.  If you’re using a version that has a QD installed in some form or fashion, you can pressurize it on a keg and then take it off.  There will be a small drop when you take it off, but the pressure should remain steady after that.  If it’s going down, make sure everything is tight.  If you don’t have a QD… spray with Star San or soapy water until you are leak free.
  2. I’ve found the scale on the adjustable PRV that I’ve used – Control Devices CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4″ Male NPT – to be largely unhelpful. This is the reason that a gauge, in my opinion, is essential.
  3. Setting desired pressure can be tricky. See our tips for making that easy.
