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.

Announcing: BlowTie Diaphragm Spunding Valve Complete Kit from MoreBeer!

BlowTie Diaphragm Spunding Valve Complete Kit

BlowTie Diaphragm Spunding Valve Complete Kit

More Info

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

With this complete kit you’ll be ready to use the BlowTie Spunding Valve right out of the box. The BlowTie 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.

Kit Includes:

  • BlowTie
  • Pressure Gauge
  • Ball Lock Disconnect
  • Duotight Tee & Flared Duotight Fitting
  • 2x Lengths of EVABarrier 8mm OD Tubing

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.

Until now, this has only been available as individual components (parts list below) via MoreBeer.  I’m excited to say that they are now selling it as a complete kit.

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.

Note: The very end of the pressure relief valve can be adjusted by unscrewing the knurled adjustment knob. If too tight and not adjustable by hand, wrap a towel around the adjustment knob and loosen with pliers. Then finger tighten or loosen to desired pressure.

Build a Spunding Valve! – New Ready Made Options

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.
