Rancilio 24V Water Inlet Solenoid Valve (Lucifer / Parker-Hannifin)
OEM-spec 24V DC solenoid valve for water inlet control on Rancilio machines, built around the Parker-Hannifin Lucifer valve body (#121FS1651B) with a ruby-seated 3.5mm orifice for precise, long-life flow control.
SPECIFICATIONS
- Coil: 481865C2, 9W, 24V DC
- Max incoming pressure: 10 bar
- Orifice: 3.5mm ruby seal
- Fluid temperature range: -40°C to +140°C
COMPATIBILITY
- Fits: Rancilio espresso machines using the two-way flange-base water inlet solenoid
- Replaces: Rancilio 34040027 (superseded), current Rancilio 340400013, Parker-Hannifin 121FS1651B
INSTALLATION
A moderate-skill swap, de-energize and drain the water line first, then unbolt the flange base; a technician comfortable with basic plumbing and wiring can handle it, but confirm orientation before reconnecting.
PRO TIPS
- If your machine is intermittently under- or over-filling, or won't fill at all, this solenoid, not the pump or probe, is often the actual culprit; the ruby orifice seat wears and stops sealing cleanly over years of mineral-laden water.
- Match the coil voltage exactly (24V DC here), swapping in a 24V AC or 110/230V coil by mistake will burn it out or fail to actuate.
