Valve body SCHAERER Spare Parts 3322739000

A valve body in an espresso machine controls the flow of hot water and steam through the internal circuits. It opens and closes ports to direct water to the group head for extraction or to the steam wand for frothing, ensuring the correct pressure and volume reach each outlet without mixing the two streams.

The operator does not interact with the valve body directly during normal use; it is installed inside the machine by a technician. Once fitted, the valve body responds to signals from the machine's control board, switching between water and steam modes as the barista selects them.

This SCHAERER valve body is moulded from PPSU, a high-performance polymer chosen for its resistance to heat, pressure and the chemicals used in water treatment. The material does not corrode or scale, maintaining a smooth internal surface that keeps flow rates consistent over time.

The part is a direct replacement for SCHAERER espresso machines that use the 2/2 2.6 specification. It fits the models listed in the SCHAERER spare-parts catalogue under article 3322739000.
