Spike PRV
Product is solid, easy to use, easy to adjust, easy to clean, and helps make great beer. There maybe cheaper options, but there isn’t a better option to ferment under pressure.

Great PRV!
I bought 2 of them for both my CF15s and couldn't be happier with them! They worked flawlessly pressure fermenting a lager at 68 degrees and an ale at 75, both done in 5 days before cold crashing. This has been a very positive way to ferment!

Awesome Product!
These are great! They work wonderfully when pressure fermenting.

You can hear it, but you can’t see it
It’s good, no question about it. There is a little flaw in the design. Gas escaping along the stem. One more O ring will solve the problem. You can hear the escaping CO2, but you can’t see bubbles. Spraying with Starsan will do.

Worth it
Works like it should. Even dealt with some krausen trying to fix a leaky lid
Adjustable
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.”

All-In-One
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.
