These are purpose built high quality valves KegLand. Not just hardware store pieces like the competitors.

The BlowTie Spunding Valve 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. 8 mm Duotight fittings at both inlet and outlet make this unit perfect for use with EVABarrier 8 mm OD tubing. The blow off pressure can be set by either pairing the BlowTie with the included Push-In Pressure Gauge, or by attaching it to an empty keg that has been pressurized to the desired psi.

Specifications:
Made from food grade acetal
Stainless screws
Easily disassembles for cleaning
8mm (5/16″) Duotight fittings at both ends
0-23 psi pressure rating (Other psi regulator faces available that you can swap out 0-60psi sold separately for a great price!)
Two functions in one great piece of hardware!

The Ball Lock QD Adjustable Pressure Valve W/Gauge can also be used to relieve pressure while filtering from one keg to another. At the same time it gives you the ability to read the pressure in the receiving keg. And Ferment under desired pressure!

If you prefer it sent with a Pin Lock type quick disconnect instead of the ball lock, please leave a note to seller at checkout, otherwise we will ship with ball lock type.

The BlowTie 2 features an integrated pressure gauge so you can quickly and easily dial in your pressure setting. The gauge is removable and can be swapped out with a gauge of a different pressure range.

Specifications:
Made from food grade acetal
Stainless screws
Easily disassembles for cleaning
8mm (5/16″) Duotight fittings at both ends
Interchangeable pressure gauge
Gauge reads from 0-15 psi
WARNING: Do not exceed gauge pressure. Exceeding the pressure range will damage the gauge.
