Danfoss Solenoid valve 071N3010

Danfoss Solenoid valve 071N3010 is a normally open valve for the secondary stage of Danfoss BFP 52 oil pumps. It controls fuel flow to the nozzle, lifting the plunger when energized and closing sharply when de-energized to prevent post-drip. The valve weighs 0.03 g and includes a spring washer and nut for installation. It is categorized as an oil filter component.

Parts of this type are selected by matching the electrical rating (coil voltage and power), hydraulic connection size and thread, and physical mounting pattern. The valve must be compatible with the pump model and burner control output. Before ordering, verify the coil resistance with a multimeter and inspect the plunger movement. Ensure gasket or o-ring seals are intact to avoid leaks.

Common failure modes include coil burnout due to overvoltage or thermal stress, sticking or worn plunger, and debris blocking the valve seat. Symptoms may include improper fuel flow, burner shutdown issues, or post-drip. Check coil resistance and plunger movement, and inspect seals for leaks.
