Conti Espresso Machine Vent Valve 1/4" – Boiler Anti-Vacuum Valve Replacement espresso grinder Reconnect terminals securely — aWhat Is a Boiler Vent Valve? The boiler vent valve (also called an anti vacuum valve or anti siphon valve) is a small but critical safety and functional component on your Conti commercial espresso machine. With a 1 4" male (BSP) connection, it allows air to enter the boiler during cool down, preventing a vacuum from forming that could collapse the boiler or cause water to siphon back into the mains supply. It also vents steam during initial heat up.
