Diaphragm Spunding Valve - Push Fittings

43 reviews

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. 

A spunding valve 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 (fermentasaurus for instance) then join the 2 liquid post together with 2 liquid disconnects and a length of beer line.

Attach the spunding valve with a gas disconnect to the empty vessel (mini keg for example). 

Set the pressure on the regulator to 12-14psi and then unwind the spunding valve 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 the fermentasaurus, 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 to transfer under pressure to stop it losing the carbonation while warm though.

Keg-to-keg transfer made easy !

I had the older version of this system made in brass and was happy about it. I needed a second one and saw that the system had been improved. I have now used the new system to transfer my beer from a polykeg 30L to soda kegs 18L and it works perfectly. I am able to transfer in isobaric conditions without loosing gas in my beer. I recommend this product. Cheers

Neat little thing

First it looks a little bit confusing and breakable but works perfectly fine!

Bisschen wackelig, aber super Preis-Leistung!

Funktioniert echt gut, sollte aber irgendwo "anlehnen". Vielleicht binde ich mal einen Schaschlikspieß drumrum, dann hält es auch so.
