BlowTie Diaphragm Spunding Valve Complete Kit
Description
The BlowTie Spunding Valve complete kit is used to release excess pressure on a pressurized fermenter or from a keg while doing pressure transfers. Thanks to the large surface area of the diaphragm, this style spunding valve is much more accurate than the poppet style. The blow off pressure can be easily set using the included Push-In Pressure Gauge. The kit includes everything you'll need to use the spunding valve right out of the bag.
This works just as advertised. It is better than the spring and poppet style. Air flow is easy to hear letting you know flow is coming through. I was able to perfectly dial in the pressure I wanted and it held that pressure without any problems.
I used the unit in conjunction with the automatic flow stopper when pressure transferring carbonated beer from my unitank.
