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.

Kegland DuoTight BlowTie Ball Lock Spunding Valve v2 with Gauge – In Stock at William’s Brewing

DuoTight BlowTie Spunding Valve With Gauge

DuoTight BlowTie Spunding Valve With Gauge

More Info

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

The BlowTie is a diaphragm based adjustable spunding valve used to release pressure from kegs and other pressure vessels. It features a usable range of 5 to 40 PSI, and the diaphragm construction means it has a wider pressure range than spring based spundling valves. This unit can be easily dissassembled for cleaning using a phillips head screw driver.

Instructions: 1. Cut good quality tube (such as EVABarrier 5mm ID x 8mm OD tubing, item Z91) cleanly with tube cutter making sure the end of the tube is a clean cut.
2. Push one end of the tube to the inlet side of the BlowTie (look at the direction of the arrow) and the other end to your pressure vessel that is releasing gas.
3. Use the yellow adjustment knob to control the pressure coming out of the pressure vessel. Clockwise is higher pressure and anticlockwise is lower pressure.

NOTE: If you would like to get a pressure reading so you can see what pressure is in your pressure vessel then we recommend: 1. Purchasing a Duotight Push in Tee (item Z95) and installing this on the inlet tubing side of the BlowTie. 2. Purchasing a 8mm Push in 0-40psi Gauge (item Z97) and pushing this into the Tee Piece. You will also need two C70 1.5″ 8mm Tubing Pieces (optional above).
This valve has a 0-40psi pressure rating


 

A Spunding Valve allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and lots more. See: Build a Spunding Valve – for loads of information on building and using a Spunding Valve.

  • The original BlowTie was awesome.  See my Hands on Review of v1 here – Hands on Review: Kegland BlowTie Diaphragm Spunding Valve
  • This is a v2 assembly.  The big difference between v1 and v2 is the v2 BlowTie has an integrated gauge.  That’s a huge improvement.
  • I’ve been keep an eye on MoreBeer’s offering for a while as it’s been out of stock.  As of this posting, Wiliam’s Brewing has these in stock at $19.99.
  • Shipping is free or reasonably priced flat rate to addresses in the lower 48 states depending on your order size for most items.

BlowTie Diaphragm Spunding Valve! – $12.99 + Free Ship Eligible, Limited Availability

 BlowTie Diaphragm Spunding Valve FE960

BlowTie Diaphragm Spunding Valve via MoreBeer

More Info

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

The BlowTie 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.

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 to 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. Dialing in your desired pressure is very simple. Although you would ideally use the BlowTie with the Push-In Pressure Gauge (D1160) and Duotight Tee Fitting (DUO109), as seen in the example photo, you can easily set the blow off pressure without it. To do this, simply pressurize an empty keg to your desired psi using your CO2 regulator. Before attaching the BlowTie to the gas post, be sure to turn the dial clockwise until it is fully closed. Once attached, slowly turn the dial counterclockwise until gas starts coming out, then slightly turn the dial back to stop the gas flow. The BlowTie is now set to your desired pressure.

Specifications:

  • Made from food grade acetal
  • Stainless screws
  • Easily disassembles for cleaning
  • 8mm (5/16″) Duotight fittings at both ends
  • 0-40 psi pressure rating
