Spike All-In-One Pressure Relief Valve (PRV)

This is our favorite pressure relief valve for fermenting vessels! We’ve tried a few valves but this is the safest and most effective one. The large valve helps prevent clogging, the air-lock and pressure knob are easy to use, and the pressure dial is always accurate.  The design also allows for spunding, letting you naturally carbonate your beer for a quicker fermentation process. Awesome! The Spike All-In-One Pressure Relief Valve (PRV) puts your safety first without compromising on features or functionality. And when you’re dealing with pressure, that’s pretty darn important. The main adjustable knob is made of an engineered plastic, and leads to smooth threading against the fine threads in the stainless steel body and can dial in pressure setting with ease.
