While this spunding valve may look a little different compared to the more common brass one with the poppet valve on the end after a lot of testing we believe this to be a superior design.
The diaphragm valve is much more accurate and allows for extremely precise adjustments of the outlet pressure.
This makes it perfect for doing fermenter to keg and keg to keg transfers under counter pressure without having to worry about overflow damaging the gauge.
Aspundingvalve is an adjustable pressure relief valve with a gauge attached to show internal vessel pressure.
They are most commonly used to do keg to keg transfers of carbonated liquid under pressure.
To do this attach your regulator to the full vessels gas inlet post (fermentasaurusfor instance) then join the 2 liquid post together with 2 liquid disconnects and a length of beer line.
Attach thespundingvalve with a gas disconnect to the empty vessel (mini keg for example).
Set the pressure on the regulator to 12-14psi and then unwind thespundingvalve until gas begins to vent. Set pressure to 8-10psi on it and the liquid will transfer across under pressure without losing any carbonation.
It can also be used to set a release point for pressure in thefermentasaurus, this is very useful as you can set it to approx 12 psi (depending on fermentation temperature) and once finished the beer will already be carbonated (you will need to either chill the fermenter to allow the liquid to hold carbonation while you bottle or use the method outlined above totransferunder pressure to stop it losing the carbonation while warm though.
