Put your brew circuit back under full control with this factory-spec 2-way solenoid valve, part M19905791. Featuring 1/4″ BSP parallel ports and a 2.5 mm orifice, the 501C-series valve regulates fill and discharge with millisecond accuracy, ensuring stable pressure and cleaner extractions. The matched 491514Q3 D4G coil draws just 13 / 11 W at 220–240 V, 50–60 Hz, delivering cool, silent actuation that protects surrounding electronics. Built in Italy from food-grade brass and high-temperature seals, it resists scale build-up and maintains leak-free performance through thousands of duty cycles. Swap it in during routine maintenance and enjoy reliable water management shot after shot.
