Spund - Ball Lock Spunding Valve G2 - Variable Pressure Release Valve - PRV

The SPUND!
Super easy to use & compact adjustable spunding valve. This is handy for keg transfers or pressurised fermentation to limit oxygen exposure. Also can be used with counter pressure in the keg you are filling into or in the fermenter you are using.

This new improved G2 model has several upgrades:
It works right out of the box but has several upgrade options

1. 8mm duotight fitting where the gauge attaches
- Allows for a range of different options such as digital gauge or larger guage to be purchased separately and upgraded.

2. Manual ring pull pressure relief + Adjustable Pressure Knob
- Allows to adjust the pressure with the black rotary knob and also use the ring pull to instantly release pressure if you want to release pressure manually.

3. Option for different set pressure PRVs to be used (purchased separately)
Yellow - 1.2bar (17psi)
Red - 2.5bar (35psi)
Green - 4.5bar (65psi)
Grey - 7bar (100psi)

This is a super low profile PRV option of only 4.5cm in height. 
This spundy valve fits to standard gas posts on your fermenter or keg.

A spunding valve is an adjustable pressure relief valve with a gauge attached to show internal vessel pressure.

Perfect for pressure brewing / pressure fermenting in your current systems or with the Fermzilla

This Adjustable/Variable Pressure Relief Valve (VPRV / PRV) or Spunding Valve with gauge allows you to relieve pressure while filtering your beer from one keg to another while keeping a closed system.

Use this to help set CO2 pressure in Kegs. Great for those who want to naturally condition or also great for keeping pressure when running beer through filters

You can also use the VPRV to naturally carbonate beer in a keg by setting the desired pressure and leaving it to carbonate. No issues with over carbonation anymore!

Adjust the pressure by turning the end of the PRV. Simply turn until the desired pressure is maintained.

Gauge face reads 0-120 psi.

Keg transfers of carbonated or un-carbonated liquid under pressure:
First, pressurise an empty keg to the same pressure as your full vessel you want to transfer from. (around 12-15psi)
Then attach your regulator to the full vessels gas inlet post (fermentasaurus or full keg 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 12-15psi and then unwind the spunding valve until gas begins to vent. Set pressure to 8-10psi on the spunding valve 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 12-15 psi (depending on fermentation temperature) and once finished the beer will already be mostly 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 if it is warm however.
