Duotight - Blowtie 2 Spunding Valve /Pressure Relief with Integrated Gauge 0-15psi

  • $39.99



Historically, the Blowtie has been one of the most popular and reliable spunding valves in the market.  Many customers used this spunding valve in combination with the FermZilla pressure rated fermenters or KegMenters.

Due to the popularity of the Blowtie we decided to make a new "Blowtie 2" and this new upgraded model has integrated pressure gauge.

This awesome compact solution for adjusting residual pressure in your fermenter makes pressure control easier than it's ever been.  This can be used for compressed air, CO2, nitrogen, mains water supply and many other things but it's primary use is to control the residual pressure inside fermenters.

The unit is made from food grade engineering plastic, stainless steel and quality made EPDM seals. 

The design utilizes the reliability of the KegLand patented duotight o-ring system to make sure you can fit hoses to this unit quickly and with leak free connections.

 

Pressure Fermentations
With pressurized 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 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.

Instructions:
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.

 

NOTEThese gauges are accurate to about 10% of the range of the pressure gauge.  So if you use the lowest range possible it will ensure the best possible accuracy.

IMPORTANT WARNING: Do not exceed gauge pressure.  If you set a gauge pressure higher than the graduations on the gauge you can damage the gauge.  (ie if you are using the 0-60psi gauge. Do not set pressure above 60psi or damage to the gauge may occur.

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 disassembled for cleaning using a Philips head screw driver.
