12V flameout solenoid valve designed to work with L2E, L3E, S3L, S4L engines as well as EC15 and EC13 models for use in a range of machines. Sturdy metal construction minimizes circuit loss and improves copper wire conductivity to help manage overheating and prevent leakage. Easy to with compatible part numbers SA 3725 12 and 30A87 20404, providing a straightforward maintenance solution for worn components. Maintenance is key: regular inspection and timely replacements or repairs help prevent leakage or overheating during operation. Functional and performance notes: reliable flameout control in 12V systems; durable metal build supports long service life and steady operation. Compatibility and size: standard 12V coil suitable for engines L2E, L3E, S3L, S4L and EC15, EC13 models. Use scenario 1: installed on small engines in lawn and garden equipment to ensure safe shutoff and reliable operation. Use scenario 2: used in compact generators or portable machinery (EC15/EC13 models) to prevent fuel flow when shutdown is required. Use scenario 3: during scheduled maintenance in machinery using L2E/L3E/S3L/S4L engines, enabling easy replacement of worn solenoids to maintain system safety and performance.
