La Pavoni Safety Valve Arm, Chrome The chrome safety valve arm that vents steam away from the machine if the boiler over-pressurizes. SPECIFICATIONS La Pavoni part #: 3432334 COMPATIBILITY Fits: La Pavoni lever machines using this safety valve arm INSTALLATION DIY-friendly swap, but confirm the safety valve itself is functioning correctly after reinstalling. PRO TIPS This is a safety component, not just cosmetic, if the arm is bent, corroded, or the valve doesn't vent freely, replace it rather than bending it back into shape; a stuck safety valve is exactly the failure mode it exists to prevent.
