Fermzilla BlowTie Spunding Valve Kit

This kit has been designed for simplicity and ease of putting together.

If you want to control the pressure retained in a pressure vessel that is releasing pressure then the BlowTie Diaphram Spunding Valve is the tool for the job.  The adjustment knob on the top of the unit makes it easy to increase and decrease the set pressure.

This BlowTie unit can be easily dissassembled for cleaning using a phillips head screw driver.

This Kit Includes:

  • 1 x Blow Tie Spunding Valve
  • 1 x duotight 8mm tee piece
  • 1 x duotight FFL to 8mm fitting
  • 1 x 8mm Push in 0-40psi Guage
  • 1 x Premium Ball Lock Disconnect (MFL) Grey/Gas
  • 2 x NEW Black 8mm straight joiner pieces


Pressure Fermentations
With pressurised fermentation becoming ever more popular it has become increasingly important to have a method of regulating and controlling this residual pressure from the fermentation process.  The BlowTie has been designed specifically for this reason.

Pressure Transfers
When transferring from keg to keg, keg to bottle, or fermenter to keg it's often a good idea to have head pressure in the keg you are filling into especially if you are transferring a beverage that is carbonated. For this reason the BlowTie can consistenly control this head pressure giving you more consistent results and without losing carbonation in the process.

Traditional spunding valves that use a simple spring against a seal are flawed right from the beginning as the physical aspects of the design dictate that you will have a significant difference between the opening pressure and closing pressure during opperation.  Brewers have tolerated this imperfection for long enough and now you can control these pressures far more accurately.

The BlowTie has been made completely differently taking advantage of a diaphragm to actuate the sealing mechanism that will release pressure from the pressure vessel with much more accurate control pressure.

Use the yellow adjustment knob to control the pressure coming out of the pressure vessel.  Clockwise is higher pressure and anticlockwise is lower pressure.
We would recommend gassing a keg to a known pressure e.g. 15psi then attach your Blow Tie Kit to the keg and adjust to 10psi.
