Pressure Relief Valve for Rancilio Hydraulic Module (Post-2013) OEM pressure relief valve built into the Rancilio Hydraulic Module produced after 2013, current Rancilio part #101000035 (Hydraulic Block MC 120V 60Hz IDR.MC 2022), superseding earlier numbers 69140028, 69140062, and 69140009. If your machine is over-pressurizing, weeping from the hydraulic block, or the brew pressure won't settle, this valve is worth inspecting first. COMPATIBILITY Fits: Rancilio machines with a Hydraulic Module built after 2013 Replaces: Rancilio #101000035 (formerly 69140028, 69140062, 69140009) INSTALLATION This is a special order item, typically requiring 6-10 business days for processing prior to shipping; installation into the hydraulic block should be handled by a qualified technician. PRO TIPS If your machine still uses one of the earlier part numbers (69140028, 69140062, or 69140009), this current-production valve is the correct direct replacement, Rancilio has since consolidated all of them into 101000035.
