This new conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. ⁠ ⁠ The paddle valve controls pre-infusion while the volumetric pump is working at full pressure, allowing the barista to perform pre-infusion on one group while the other is extracting coffee. ⁠ ⁠ This dynamic system allows the barista to reduce channeling for a more balanced extraction and also has a longer lifespan than the old MP valves.⁠ ⁠ The conical paddle retrofit kit upgrades an original MP (mechanical paddle) group to the new conical valve. ⁠ ⁠ Available as Spare Part through our Offical Spare Parts distributor. nuovaricambi⁠ Retrofit Kit codes:⁠ 934 (Linea Classic and GB5)⁠ 954 (GS3 and Strada)⁠ ⁠ #lamarzocco⁠⠀⁠ #lamarzoccoparts #techtuesday #spareparts⁠⠀
