La Pavoni safety valve M22

The boiler safety valve on this page can be found on older espresso machine models of La San Marco. There is for this part no la San Marco part reference number.

This safety valve has a male M22 thread with a pitch of 1,5mm. The valve has been calibrated on 1,8bar. When the valve opens it can release up to 6,3 kg/h of steam. This valve is auto certified and made in the EU.

If you have a older La San Marco espresso machine, check the safety valve which came out of the machine for its threads. To see if it’s not the modern version
