The BlowTie Diaphram Spunding Valve - a great tool if you want to control the pressure retained in a pressure vessel that is releasing pressure. It has been designed for simplicity and ease of putting together. Many brewers use this spunding valve in combination with the FermZilla pressure rated fermenters.

This is the new "BlowTie 2" upgarded model which has the integrated pressure gauge. 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 screw driver. Designed to suit 8mm (5/16") tubing. It's compatible with both the 4mm ID Tubing or 5mm ID.

This 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 its primary use is to control the residual pressure inside fermenters.

Specifications:
1. Suits pressures 0-15psi (but with different gauges the unit can go above 100psi)
2. Made from food grade acetal
3. Stainless screws
4. 8mm (5/16") push on both sides

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