Control Devices Adjustable Pressure Relief Valve [0 to 100 PSI]

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.

Inline CO2 Regulator [control each keg separately] + Hands on Review & Hacks

in Line Plastic RegulatorIn Line Plastic Regulator

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

  • A small barbed regulator for use with liquid or gas
  • Made from acetyl, nitrile, brass and stainless steel parts
  • Controls pressure from 0 – 150 psi
  • Includes 3/16 inch

Notes from HBF: This is an inline secondary regulator.  You still need a primary regulator attached to your CO2 tank.  The idea is, you set the primary to the highest pressure you will use (without exceeding specifications of any component of your system) and then use these regulators inline (one per line) to fine tune pressure and carbonation [See: Balancing Your Draft System].  As an example, you could set your primary to 25 PSI for faster force carbonation and set each line to a different pressure based on desired carbonation level.  Since this does not have a gauge, you need some sort of a gauge to use for tuning this in.  The gauge doesn’t have to stay connected, just while you’re setting the regulator.  This is a perfect application of a Spunding Valve [See: Build a Spunding Valve! – How and Why]

Spunding Valve Build: Using Primefit CR1401G Replacement Air Regulator

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

Most of our builds consist of a PRV Valve + tee + gauge + connection option.  Generally four parts in total.  The build detailed in this post utilizes Primefit’s CR1401G Replacement Air Regulator.  That one piece replaces the tee and gauge.

The components I used for this build.  See below for parts list.A look at the Primefit CR1401G Replacement Air Regulator with steel-Protected Gauge, 1/4″ NptThe completed assemblyBottom view of the completed assemblyA top down look at the assembly.  For a Spunding Valve application the red pressure knob clearly visible here is not particularly helpful.  The PRV is doing the heavy lifting.  I set this to full flow.Another version utilizing the a BlowTie PRV valve.

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″.

BlowTie PRV Option

This option requires a BlowTie Diaphragm Valve + a small piece of 8 mm” ID EVABarrier Tubing + a Duotight 8mm ¼” NPT Adapter

One of My Favorite Gadgets: Inline CO2 Regulator [control each keg separately] – $5.99

Inline Secondary Regulator via MoreBeer!

More Info

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

An ideal solution if you want to serve different beers at different gas pressures. In a typical multiple line, multiple pressure system you would run a gas line from you main regulator into a secondary regulator where you would set different pressures. While that is ideal it is a little pricey. This little sweetheart lets you set different pressures at a far lower cost. What we do is set the main regulator at the highest pressure we want in the system – for example a keg of soda that you want to carbonate and serve at 25 psi. Run the gas line into a manifold and then install one of these after the manifold on each line where you want to decrease the pressure, for example lowering to 10psi to serve your British pale ale and 14 psi to serve your summertime lawnmower lager.

While this unit does not have a pressure gauge you can use an adjustable relief valve/spunding valve on your keg to tell the pressure. Pressure adjusments can be made with a screwdriver.

The maximum inlet pressure is 150 psi. Made from non corrosive acetyl, nitrile, and stainless parts. The regulator comes with two brass barbs to fit 3/16″ tubing on. Alternatively, you can remove the barbs and use 1/4″ tubing directly on the regulator. The aluminum manifolds linked above feature 1/4″ barbed outlets and are a good match with this regulator.

  • Works with 0 – 150 psi
  • Works with both gas and liquid
  • Comes with two brass barbs
  • Has two mounting points
  • Made from non corrosive acetyl, nitrile, and stainless parts

 

But Why??

  • This thing is awesome: This is an inline secondary regulator.  You still need a primary regulator attached to your CO2 tank.  The idea is, you set the primary to the highest pressure you will use (without exceeding specifications of any component of your system) and then use these regulators inline (one per line) to fine tune pressure and carbonation [See: Balancing Your Draft System].  As an example, you could set your primary to 25 PSI for faster force carbonation and set each line to a different pressure based on desired carbonation level.  Since this does not have a gauge, you need some sort of a gauge to use for tuning this in.  The gauge doesn’t have to stay connected, just while you’re setting the regulator.  This is a perfect application of a Spunding Valve [See: Build a Spunding Valve! – How and Why]
