Description

La Marzocco Steam Valve Rebuild Kit – KB90 / GB5 X-S

A genuine La Marzocco service kit for rebuilding the steam valve assembly used on KB90 and GB5 X-S commercial espresso machines. It provides the service components required when maintaining the internal valve rather than replacing the complete valve assembly.

Steam valves operate under regular heat and mechanical use, so internal seals, O-rings and spring components can wear over time. Rebuilding the valve with the correct components can help restore proper valve operation and sealing.

The KB90 is designed with an easily serviceable steam valve that can be accessed from the front of the machine. As this is an internal steam-system service item, installation by a qualified coffee machine technician is recommended.

Confirm manufacturer part number 1206 against the machine parts diagram before ordering, particularly where machine generation or valve configuration is uncertain.
