BLOWTIE DIAPHRAGM SPUNDING VALVE

If you want to control the pressure retained in a pressure vessel that is releasing pressure then the BlowTie Diaphragm 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 unit can be easily disassembled for cleaning using a phillips head screwdriver.

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 Blow Tie can consistently 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 operation. 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.
