Control Devices Adjustable Pressure Relief Valve [0 to 100 PSI] – $10.59 + 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.

Kegland DuoTight BlowTie v2! – $16.99 via DuoTight Sale + Freebie w/Qualifying Order

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.
  • As of this posting William’s Brewing has this for just $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.

Save 15%!

  • For a short time, William’s Brewing is discounting DuoTight fittings by 15%
  • No coupon code is required.  Discount reflected at checkout.  That makes this just $16.99 at checkout.
