The BlowTie is a diaphragm based adjustable spunding valve used to release pressure from kegs and other pressure vessels. It features a usable range of 4 to 15 PSI, and the diaphragm construction means it has a wider pressure range than spring based spundling valves. This unit can be easily disassembled for cleaning using a phillips head screw driver. Accuracy of the gauge is plus or minus 2 PSI.
Instructions: 1. Cut good quality tube (such as EVABarrier 5mm ID x 8mm OD tubing, item Z91) cleanly with tube cutter making sure the end of the tube is a clean cut.
2. Push one end of the tube to the inlet side of the BlowTie (look at the direction of the arrow) and the other end to your pressure vessel that is releasing gas.
3. Use the yellow adjustment knob to control the pressure coming out of the pressure vessel. Clockwise is higher pressure and anticlockwise is lower pressure.
