Hands on Review: Kegland BlowTie Diaphragm Spunding Valve! – new section BlowTie as part of DIY Builds

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

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.

Here’s a look at each component…

Control Devices Adjustable Pressure Relief Valve [0 to 100 PSI] – $10.44 + free prime ship & Building a Spunding Valve

Control Devices CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4" Male NPT

Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4″ Male NPT by Control Devices.

More Info

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

  • Relief pressure adjustable from 0 to 100 psi
  • 1/4″ male NPT threaded inlet connection
  • Brass construction and stainless steel spring for corrosion resistance
  • Silicon O-ring provides leak-proof seal to within 10 percent of set pressure
  • Micrometer-style nylon knob for pressure relief adjustment

This Control Devices CR25-100 pressure relief valve has a brass body, an adjustable relief pressure, a 1/4″ male NPT threaded inlet connection, and a fluorocarbon O-ring. The valve’s brass body, brass valve seat, and the stainless steel poppet resist corrosion and can be used in operating temperatures up to 250 degrees F. The valve can be adjusted to open between 0 and 100 psi using the micrometer-style nylon knob. This safety valve has an 6 standard cubic feet per minute (SCFM) flow rate and is suitable for low flow pressure relief applications such as in tankless air compressors.

Relief valves remove excess pressure or vacuum from a system. The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit. They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. Some relief valves have an adjustment mechanism to set the pressure where the valve opens, making it suitable for various applications. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation.


 

This valve is the heart of my Spunding Valve Build.  It is a manually adjustable pressure relief valve.  Adjustable from 0 to 100 PSI.  I’ve found the pressure markings on this to be difficult to use/possibly inaccurate.  My Spunding Build accounts for this via a pressure gauge.  There is no homebrewing-related situation I’m aware of that would have you at 100 PSI.  Generally you’d be at or below 30 PSI.  As always, you’ll want to ensure that all components in your system (kegs, tubing, etc) are rated for your desired pressure.

Spunding Valve Build: “Cheapest Option”

Thank you to /u/workaccount32 on reddit for this photo

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.  Read lots and lots more about Spunding Valves, ways to use them and different build options on our Spunding Valve Resource Post

Cheapest Option:  Generally speaking, the brass variations of the fittings featured in our various Spunding Valve builds are probably going to be the most economical route to go.  This is a general statement and may not always be the case.  Check product pages for current prices and availability.

Components – all parts via Amazon:

Product pages may display other size variations of the fittings used here.  If a particular size is out of stock, sometimes suppliers link to another size.  All thread sizes for this build, both NPT and barbs, are 1/4″.

Brass Combo –  This package gets you two brass tees and two brass barbs: WYNNsky Metals Brass Pipe Fitting Barstock Tee 2 PCS 1/4″ x 1/4″ x 1/4″ NPT Female Pipe 2 PCS 1/4″ NPT X 1/4″ Hose ID Brass Hose Barb Fittings – this combo would replace the two Anderson Metals Fittings above

Build a Spunding Valve! – How and Why – new component options! Primefit Combo + BlowTie PRV

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.

Homebrewing Applications of a Spunding Valve

  1. Pressurized fermentation.  Ferment in a 5 or 10 gallon corny keg and use your Spunding Valve instead of an airlock.  This allows you to ferment at your desired pressure.
  2. Dry hop under pressure.  This allows you to dry hop earlier while reducing oxygenation.  Active yeast are more likely to metabolize oxygen that’s introduced during dry hopping during active fermentation.  Since CO2 is not exiting beer as vigorously under pressure, wanted compounds, flavors and aromas are more likely to stay in your beer under pressure.
  3. Naturally and accurately carbonate beer right in the keg.
  4. An airlock replacement.  Keep the valve wide open for non-pressurized fermentations.  Only do this if you have plenty of head space.  This wouldn’t make a great blow off tube.
  5. Keg to keg transfers.  Use the Spunding Valve to allow excess gas to exit the receiving keg as you transfer under pressure.  Helps you achieve a slow, controlled and pressurized transfer.
  6. Fix over-carbonated beers.
  7. Test for keg leaks.  Pressurize your keg to serving pressure.  Put the Spunding Valve on (with the pressure set well above your serving PSI) and note the reading.  The gauge should remain steady.  If pressure drops, you know you have a keg leak.  The digital build, see below, is especially helpful for this task,  The digital gauge reads with .1 PSI resolution making pressure changes easy to spot.  It’s worth noting that this checks the entire keg including gas body o-ring.  That spot is hard to check and other way as it’s only in function when the gas QD is on.  When the gas QD is on… it’s difficult to spray and check for bubbles underneath the gas QD.  Thanks to Scott Janish for this tip!
  8. As an airlock for long term aging of beers.  Airlocks can run dry over time.  A Spunding Valve will not.
