La Marzocco 1/4" Anti-vacuum Valve

1/4" Male BSP. Use CP_1 tubing, held in place with a clamp, or a small zip tie. Used in the GS3, Linea Mini, Linea PB and Strada models only. Not the same as the (1/8") one used on the steam valve of the GB5/FB80 or (old version 1/4") Linea Classic/FB70. This can be used to replace any 1/4" anti-vacuum valve.

In the Strada model it is located in the right, rear portion of the machine, by the back of the boiler.
