Aren't the ones with markings pretty unreliable? This has a gauge built right in to tell where it is. I would think a gauge like that would be more accurate and easier to read than tick marks on something that is screwed in and out. I thought it was a great idea to do it this way.
The markings at least get you into the range. No markings means you have no fracking idea where it's set to. When I carbonate, I set it to 1bar (just under 15psi) to keep it from venting what I'm infusing.

I'm holding to no marks is being short sighted. They could simply have it on the screw that moves to change the pressure release aspect. I'm not looking for high accuracy 1psi increments. 2-4 psi increments would be fine. Hell, in a pinch, 5psi would be 'OK' (but not optimal). At least give us SOME IDEA of where the setting is. Last thing I want is to start a batch, THINK I have it set where I want it, only to find out (in another day or two) that the pressure inside is either way higher than I wanted, or way lower than I wanted.

It's kind of a pain, but you could pre-set it to exactly the pressure you want by clamping a TC gas post to it, then pressurizing with CO2 while you adjust the release pressure. That's how I set my blow-tie PRV.
 
Welcome to our Pressure Fail Series. Where we chat about common myths, misconceptions and #fail's of the existing PRV's on the market.

Let's begin with what's commonly known as the Bowtie 'spunding valve'.

This design was originally intended for use in kegs, but we see users move them to the top of their conicals for pressure fermentation and spunding all the time!
🤦🏻
The tiny outlet can easily clog during a vigorous fermentation which can create a super dangerous situation. A LARGE outlet port was the first design consideration we focused on; safety first, beer second. With the new Spike All-In-One PRV, we use a full 1.5" TC port design which will not get clogged with krausen, hops, etc!

With my existing spunding valve of similar design, I pressurize my conical to 5PSI per the gauge on the Spike gas manifold and slowly open the spunding valve until it starts bubbling. I expect to do the same when I order these. Looking forward to these because it will significantly reduce the number of components I need to clean having a separate gas manifold plus the parts needed to tie in the spunding valve without having to swap parts around.
 
Pressure Fail #2

This design is also popular, but still has a very small outlet that can get clogged. Krausen or hops can get up into the outlet and clog or ‘glue’ the relief valve seal closed. A smaller outlet port means less surface area which creates less force pushing up on it. A full port design like the Spike All-In-One PRV has 7 times more surface area than this product and thus 7x the force on the plunger to prevent it from sticking closed.

Again, the goal is not to discourage people from purchasing other company’s products. The goal is to educate all brewers on what is a safe setup and what is not. We’ve seen so many unsafe pressure setups lately and we can speak for all manufacturers that the last thing anyone wants to see is someone get hurt! Safety first, beer second!

What's the gas post on the valve for? I thought this was how you set the adjustable prv.......or is it like the Spike manifold that just lets you pressurize the whole fermenter? I've not used these types of spunding valves, much less done a lot of pressure fermentations, so I'm just spitballing here.

Good idea from Tom R. Another one is take the butterfly valve (if you don't have an extra valve) from your fermenter and put it between the fermenter's port and adjustable prv valve. Use the butterfly valve to close off the prv from the fermenter to set your pressure. My guess with the butterfly closed, you can then adjust the prv to the desired pressure since gas can't escape into the fermenter. Then exhaust the gas between the butterfly and prv and put the butterfly valve back where it goes.

Then exhaust the gas between the butterfly and prv and put the butterfly valve back where it goes. It should be easier if you already have a valve used in conjunction with a hop dropper as you'd just swap the dropper for the prv since the butterfly valve stays in place.

The gas post is for adding pressure. It's useful during cold crashing or pressure transfers to a keg. The adjustment knob is at the top of the PRV.

As an FYI to everyone... NEVER put a valve before your PRV. It only takes one time to accidently keep it closed and you've essentially created a bomb.
 
@SpikeBrewing ... did this thing really sell out in under 5 minutes? Or is it not live on your website yet?

Edit- yup, looks like they sure did sell out fast per your email. Dang thing went about as tickets to Supertramp!

Sold out in less than 3 minutes!! Don't worry, we'll have plenty more during the product launch in April.

@SpikeBrewing

Bruh....About those other 4.................

We'll have more details on those in the next few weeks. Stay tuned!

Good catch. I've edited out the last part of my post as it can easily be misunderstood as me suggesting that. That truly wasn't my intent. My apologies everyone.
 
A lot of people have been asking about our new All-In-One PRV in comparison to other products on the market. In the below video Ben (Owner of Spike) and Adam (Head of Engineering) sit down and discuss the pros and cons of what is currently on the market as well as the differentiators of the new Spike All-In-One!

Any word on when the backlog might loosen up? I'm just about finished configuring a 7.6 gallon kegmenter to be a brite tank and the (almost) last piece is a proper spunding valve. I really like the one on my SS Brewtech unitank, but that new Spike spund sure has my attention. Availability will be the determining factor, and time is running out for when I'll need it.
 
how tall is this item? I've got the old lid and am wondering if maybe I could put a tee on the single port in the sideways orientation so this spunding/prv would be at very top. On the center port on the tee I would put a valve and blow off tube. Need to understand if the tee and this PRV would fit inside my freezer...

The first round of orders were for a presale only. Those should ship in mid-April right around the time we officially launch the product.

The PRV is about 8" tall. We do sell the 3 port lids separately. Might be cheaper to go that route than investing in a bunch of stainless piping.
 
The first round of orders..
So there will be a supply available for order and delivery by mid-April? I could probably hold off making a purchase until then, between my conical (non-pressurized) and unitank.

The kegmenter is specifically going to be used as a brite tank to spund the wort from the conical (re: 'secondary') when I get to ~5 pts. of FG, as well as conditioning prior to kegging. The all-in-one spund would solve a couple of my issues without resorting to a "Rube Goldberg" type contraption on top of a 1.5" TC. Count me in, among the motivated!

Correct! We should have plenty of stock for our full product launch in mid-April.
 
We asked for your questions on the new All-In-One PRV from all of you. Watch the video below where our engineers answer all the questions we got on our latest product which is launching in mid-April!

Here's a question:

Are you accepting advanced order purchases prior to the mid-April launch? (hope, hope... I WANT one!!)

I've watched all the videos, and it looks like you guys have hit a home run with this combo spunding valve. Spunding, gas-in, pressure gauge, and PRV, all in one ingeniously designed 1.5" TC port mount. Well done, Sirs! Now all I need to do is actually get one.

We did have a preorder about 3 weeks ago. Those are all accounted for, sorry!
 
This is a very thoughtful design. I have a SS spunding valve on my 14 gallon unitank but need one for my 7 gallon. I think at this price point you can’t beat it.

The advantage I see in replacing the spunding valve on my SS Brewtech unitank with this combo from Spike is versatility.

I'm thinking that mounting this combo on top of the tank (in place of the existing 1.5" TC PRV & vacuum breaker) would combine those functions plus add pressure gauge, gas 'in' QD, spunding, pressure dump, etc., into a single device. That would eliminate the need for the existing vertical manifold and free up a 1.5" TC port on top of the tank for a hop dropper.

The downside of this would be that it creates a single point failure potential if the top TC port ever got blocked, though I think it would be a very low probability that krausen could reach that high even in the most vigorous fermentation.
