Finally an affordable option for those looking to get into pressure fermentation without the extra cost of extra spunding equipment.
This Purple Pressure Relief Valve can be used to keep 15psi of pressure on your lager or ale ferments in our Fermenter King P.E.T. Pressure Fermenter/Unitank range.
The purple PRV will lift when pressure exceeds 15psi and will reseal at the end of fermentation when the pressure drops back.
Please note there will be a hissing noise throughout fermentation when using these PRVs.
Brewers will need to replace the purple PRV with the red PRV to carbonate at pressures higher than 15psi.
