Danfoss solenoid valve 071N0050

This is a normally closed solenoid valve assembly (valve, nut and washer) for Danfoss BFP oil burner fuel pump assemblies. It is intended for pump sizes 2, 3, 4, and 5, and fits the Danfoss BFP models including BV69, BV77, BV110, BV170, BV290, B230, B360, BV100, BV160, and BV280. It is also catalogued as 4031.195.

Parts of this type are selected by checking the electrical supply (voltage and frequency) to match the existing burner control circuit, verifying the connection thread size, and confirming the flow configuration (normally closed) used in the pump. The valve may be supplied as a complete assembly or as a coil and valve body separately, so confirm which part is actually needed. Always compare the physical fitting and electrical rating with the original before installation.

If this type of valve fails, the fuel flow may not be cut off sharply, which can cause nozzle dribble after shutdown. The burner may also fail to fire if the valve does not open. When such symptoms appear, check the valve and coil operation, and inspect the pump's shaft seal and pressure regulation, as wear elsewhere in the fuel system can cause similar issues.
