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.
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 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.
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.
1. Made from food grade acetal
2. Stainless screws
3. 8mm (5/16") push on both sides
4. 0-40psi pressure rating
Please note: The black joiners are a semi-permanent fitting. You will not be able to remove the fittings easily. If you would like to have a completely removable fitted kit we would suggest using EVABarrier 4mm ID or 5mm ID hose as the joining pieces.
