Saeco 421944029331 2-way Solenoid Valve OT57 G1/8 24V Dc

Product Description

The SAECO 421944029331 is a 2-way solenoid valve designed for use in commercial and super-automatic espresso machines. This electrically actuated valve controls fluid or steam flow within the hydraulic circuit of the machine, opening or closing a single flow path on demand. It operates at 24 volts DC and draws 10 watts, making it compatible with the low-voltage control circuits common in commercial coffee equipment. The OT57 designation identifies the valve body series, and both inlet and outlet ports are G1/8 female threaded connections. Licensed technicians and trained coffee equipment service pros handle installation and replacement of this component.

This valve is typically found in the internal plumbing circuit of Saeco-platform espresso machines, where it regulates water or steam routing between the boiler, pump, and brew group. It is suited for commercial foodservice environments as well as high-end residential installations. Replacement is most often required when the valve fails to actuate, leaks past the seat, or causes inconsistent shot pressure or steam delivery.

Key Features

• 2-way normally closed solenoid valve controlling a single flow path
• 24 volt DC operating voltage compatible with low-voltage machine control boards
• 10 watt coil power rating
• G1/8 female threaded ports on both inlet and outlet for direct plumbing integration
• OT57 valve body series for direct OEM-style fitment

Compatibility

Designed as an OEM-style replacement solenoid valve for Saeco-platform commercial and super-automatic espresso machines using G1/8 female ported hydraulic circuits operating at 24 volts DC.

Installation Notes

Installation should be performed by a qualified coffee equipment technician or licensed service professional. Before replacing this valve, disconnect the machine from mains power and depressurize the boiler fully following the manufacturer's shutdown procedure. Use appropriate thread sealant rated for hot water and steam service on the G1/8 fittings, and verify correct coil polarity on the DC circuit before restoring power. Do not energize the coil outside of the machine circuit.
