Woodward 1502ES-24C6U1B1S1 Fuel Shut Off Solenoid

The Woodward 1502ES series is an externally switched dual coil solenoid designed for fuel shutoff applications on diesel engines. It utilizes separate pull and hold coil windings to enable continuous energization without overheating. The pull coil delivers maximum force for actuation, while the hold coil maintains position at reduced current. This 24V variant (1502ES-24C6U1B1S1) features a pull force of 44-53 N and a hold force of 85-125 N. It is configured with base mounting, ungrounded screw terminals (three terminals: Battery Negative, Pull, Hold), and replaces Woodward OEM 1500-1009. Cross-references include SA-5172-24, SA-3345-T, and SA-3819. Typical applications span Lister Petter LPW series, Perkins T40, Cummins 6CT industrial engines, and equipment such as Liebherr A932 excavators, JLG aerial lifts, and Niftylift platforms.
