Anti-Vacuum Valve 3/8″ M – Brass, for Spaziale & Vibiemme Domobar

3/8″ Anti-Vacuum Valve for Spaziale and Vibiemme

On Spaziale and Vibiemme boilers this valve stops a vacuum forming as the machine cools overnight. Without it, the boiler can pull water or milk back through the wands and the steam taps. On a heat-exchanger machine it also helps the boiler refill smoothly the next morning.

Larger 3/8″ Thread

It is the same ball-in-body design as smaller anti-vacs but with a heavier 3/8″ male thread and a longer brass hex. If it hisses after warm-up, the ball and seat are usually scaled or worn. Seal the thread properly when fitting, as brass threads can strip if forced. Always work on the machine cold and with the boiler drained.
