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.  heck the product page to see if you can still order this.

Back in Stock… Stainless Steel PRV for Spunding Valves – $11.99 at Brew Hardware

stainless steel adjustable prv spunding

WELDLESS BULKHEAD WITH PIN LOCK GAS from Brew Hardware

More Info

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

1/4″ NPT threads. 100% stainless with a buna seat.

0-30psi give or take. Spring-based relief valves are not exactly precision so expect a plus or minus of a couple PSI.

Uses? Measuring carbonation level in a keg already carbonated (measure temp, measure constant pressure over an hour, refer to carbonation chart), Vent a keg that is naturally carbonating with priming sugar to avoid overcarbonation, pressure ferment in a corny (the true meaning of spunding).

We include this item in our complete spunding units.

Warning: Be extremely careful with pressurized vessels. This item is not suitable as the only means of pressure relief in a completely sealed tank because the flow rate is relatively low and it may be clogged easily such as in the case of fermentation will inadequate head space. Please consider using a secondary pressure relief method at a slightly higher pressure setting for added safety. In the case of a corny keg for example, the lid has a pressure relief that will blow before the safe pressure rating of the keg.

Note: some customers have expressed confusion or disappointment in how this unit behaves. To be very clear to avoid confusion, this unit does not have reliable visual indicators to help set the unit to vent at a specific pressure. In other words, there is no detent or marking that says “vent at 10 psi”. Spring-based vents are relatively crude devices and as such the exact venting pressure at any given knob position is only reliably gauged by pressurizing with an external source such as compressed air or CO2 and observing the vent pressure with an installed pressure gauge such as how we build our spunding valves.

Another way to say it as a practical example, if you want to set it to vent at 10 psi, you would tighten up the knob, apply about 20 psi into the system and then rotate the knob counterclockwise until it begins to vent. Watch the gauge and see where it stops venting. That is now the current vent pressure setting. If it’s higher than desired, rotate the knob a little more counterclockwise until venting starts and then stops at the correct pressure. Once you think you have it right, add more pressure to the system and make sure it vents down to the pressure once again.


 

This could be used as part of a Spuding Valve assembly.  A Spunding Valve [See: Spunding Valve Resource Post] allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and lots more.

  • As of this posting, Brew Hardware has it for $11.99.
