The Blow Tie 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 (D1717
). The blow off pressure can be set by either pairing the BlowTie with the Push-In Pressure Gauge (D1160
), or by attaching it to an empty keg that has been pressurized to the desired psi.
