Adjustable pressure release valve to suit duotight fittings.
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 dissassembled for cleaning using a phillips head screw driver.
1. Cut good quality tube (such as EVABarrier 5mm ID x 8mm OD tubing)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.
