When it comes to brewing, you don’t want to skimp on your safety.

Works great! Only criticism is that the logo was placed in-between the two holes for the release valve and gauge.

Top Notch

This product is so much better than any other that I’ve used! I brewed a Lutra lager, put it in my flex fermentor with the PRV attached and with a little fine tuning was fermenting at 10 psi and it held for the entire fermentation. Not only is it functional but I feel much safer fermenting under pressure than I used to with my old sounding valve that looked like someone pieced it together in the hardware aisle of the local Home Depot. All and all this thing is top notch

Convenient package

This little unit replaced the larger competition spunding valve setup. It was easy to dial in and worked. My only complain is that I wish it was possible to release pressure w/o having to remove the sanitized solution (or getting splashed). If there was a release value below the fluid container it would be possible and would allow for users to no longer need a dedicated PRV elsewhere. I can appreciate that having the PRV below could mean it gets clogged, but as this unit itself is a PRV that may not be a big deal.

the item is very well made and thought out.



The All-In-One PRV is fully adjustable from 0-15psi. Simply twist the top adjustment knob to increase or decrease the pressure inside your fermenter. This allows for use with everything from pressure fermenting, spunding, carbonating or even pressure transfers to kegs. Brew smarter, not harder.

Safety First, Beer Second

CO2 produced by yeast must be handled carefully, otherwise the vessel can become over pressurized, making it very dangerous. This is why a large-port robust PRV is so important. A PRV is designed to automatically vent CO2 gas from inside your fermenter at a set pressure. Since Spike fermenters are designed for 15psi, that’s what the All-In-One PRV is designed to release at. The seal and spring lifts to allow it to escape or “bubble out.”


There’s a lot of PRV options out there, but the Spike All-In-One PRV combines all those features and then some in one sleek design. It has an adjustable pressure release knob, pressure gauge, gas post, quick release plunger and sanitizer cup with drain.

Pressure and Vacuum Release

Not only does the All-In-One have an adjustable pressure release but it also has a 1psi vacuum release and quick pressure release! Done fermenting or need to bleed off pressure? Simply lightly push down on the top plunger to bleed off the desired amount of pressure from your fermenter.

02 / 03

Sanitizer Cup

During development, the number one request from BETA testers was to add a sanitizer cup. The sanitizer cup acts as an airlock to let gas escape but doesn’t let air back in which can cause an infection. The cup also has a built-in quick drain barb so you can quickly and easily drain the sanitizer before depressurizing so you don’t end up getting a sanitizer shower.

1.5” Universal Fitting

We’ve said it before and we’ll say it again—when it comes to safety, bigger is better! The All-In-One PRV uses a huge 1.5” TC fitting, which virtually eliminates the chances of it ever getting clogged. Many competitor PRVs have much smaller openings, which can get clogged with hops or krausen.
