Hands on Review: Kegland BlowTie Diaphragm Spunding Valve + v2 is back in stock

A Spunding Valve allows you to maintain a set pressure. If pressure in the vessel exceeds the set point, it is expelled. It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.


Why a Spunding Valve?

There are loads of homebrew related applications for a Spunding valve ranging from pressurized ferementation to naturally carbonating to fixing over carbonated beers and lots more.  Check out our resource post on the subject.  It’s arguably the go-to resource on the Internet on the subject


Update: New Kegland BlowTie v2!

v2 has been sold out for some time, as of this update… they’re back in stock.

Since this review was published, BlowTie v2 has been released.  The major improvement is… a built in gauge.  Look for an update to this review in the future.  General concepts should remain the same.  I recommend purchasing the newer v2.


Hands on Review Kegland BlowTie Spunding Valve

The BlowTie Spunding Valve assembly consists of the BlowTie, a DuoTight Tee Fitting, a DuoTight to flare fitting, a DuoTight pressure gauge and two small pieces of EVABarrier Tubing.

Back in Stock at MoreBeer! – BlowTie Diaphragm Spunding Valve WITH Gauge

BlowTie Diaphragm Spunding Valve with Gauge FE962

BlowTie Diaphragm Spunding Valve with Gauge from MoreBeer

More Info

From the product description, check product page for current description, price and availability:

The Blow Tie Spunding Valve is used to release excess pressure on a pressurized fermenter or from a receiving keg during pressure transfers. This diaphragm spunding valve is much more accurate than the spring and poppet style, and works much better at lower pressures.

The BlowTie 2 features an integrated pressure gauge so you can quickly and easily dial in your pressure setting. The gauge is removable and can be swapped out with a gauge of a different pressure range.

Pressure Fermentation

Pressure fermentation is becoming more and more popular at the homebrew level, but in order to do it safely and accurately you need a way to release excess pressure. You’ll pressurize your vessel to your desired psi, but once fermentation begins and those hungry, active yeast start creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when the pressure gets too high and close up again when it’s back to your desired psi.

Pressure Transfers
Even if you don’t have a pressurizable fermenter, you may have done pressure transfers from keg to keg during filtering or after fining. During pressure transfers, it’s a good idea to have a bit of head pressure in the receiving keg, especially if you’re transferring beer that is already carbonated. Having a spunding valve in place will allow you to consistently control the head pressure and give you more consistent results, without losing carbonation in the process.

Diaphragm vs. Poppet
With the poppet style spunding valve, a spring pushes against a poppet to keep the valve closed. When the poppet lifts up to open, the surface area the gas pushes against becomes larger, and the spring has to work harder to push the poppet down and reseal the valve. This can lead to more gas being released than intended, and the remaining pressure in your vessel may be at a lower psi than your spunding valve’s set psi.

Instead of a poppet, the spring inside the BlowTie pushes against a diaphragm, which has an immensely larger surface area. This means the surface area that the gas pushes against while the diaphragm is closed is significantly closer to the surface area it pushes against when the diaphragm is open. This leads to higher accuracy, and the remaining pressure after excess gas is released will be much closer to your set blow off pressure.

Set Up
The BlowTie spunding valve comes with 8 mm Duotight fittings on the inlet and outlet, and we recommend using it with EVABarrier 8 mm OD tubing (D1717 or D1718). You’ll also need the flare Duotight fitting (DUO106) in order to attach it to a ball lock or pin lock disconnect. Dialing in your desired pressure is even easier with the BlowTie 2, thanks to the integrated pressure gauge. Simply start with the adjustment knob fully closed, then slowly open it until the gauge reading matches your desired pressure setting.

Specifications:

  • Made from food grade acetal
  • Stainless screws
  • Easily disassembles for cleaning
  • 8mm (5/16″) Duotight fittings at both ends
  • Interchangeable pressure gauge
  • Gauge reads from 0-23 psi

WARNING: Do not exceed gauge pressure. Exceeding the pressure range will damage the gauge.


 

  • DuoTight Fittings and Accessories along with EVABarrier Tubing are… awesome.  In my opinion, the system is a game-changer for kegerator owners and builders.
  • The BlowTie is part of that lineup.
  • This is v2.  The big innovation is that v2 includes and integrated gauge.  Check out my Hands on Review of the v1 BlowTie Valve
  • This has been sold out for a good bit.  As of this posting, it’s available again.  check the product page to see if you can still order this.
  • Get Free Shipping: This ships for free with a qualify order as part of MoreBeer’s Free Shipping Program.  Under that promo most orders over $59 ship for free.
  • Easy Filler Item….  If you’re looking for a filler item to help you qualify for free shipping, consider grabbing some PBW

Oxygen Free Transfer and Cold Crash Using a Spunding Valve

What is Cold Crashing?

Cold Crashing is chilling your beer after fermentation is complete.  Typically you want to get as close to freezing as possible, without actually freezing your beer.  These cooler temperatures cause break, yeast and trub matter to drop out of your beer.  This increases clarity, helps to hasten the conditioning process and helps you get a cleaner transfer to your serving vessel.
