Rancilio Expansion Valve Spring

Rancilio Expansion Valve Spring

Replacement spring for the very old Rancilio expansion (over-pressure) valves. These are only used in models that are now so antiquated that this spring is a special order item from Italy only. Long delays and limited stock may affect availability.

SPECIFICATIONS

• 10 x 26 mm

COMPATIBILITY

• Fits: Rancilio S-20, Z-11 and V.1 Epoca

INSTALLATION

This may be a challenging task, part of an expansion valve rebuild.

PRO TIPS

• A weak or fatigued expansion valve spring is a common cause of erratic brew pressure or a valve that dumps water prematurely, if you're chasing an inconsistent pressure gauge reading, this inexpensive spring is worth replacing before assuming the whole valve body has failed (and is unavailable).
