Volvo FH/FM/FMX Solenoid Valve 21472978 23439998 24145125 24V Euro 6 Used Horn Valves & Pulls

Description:
This listing is for a genuine Volvo pneumatic solenoid valve, OEM part number 21472978, rated 24V and 1.0 MPa. It is used in the compressed air / braking and chassis control systems on modern Volvo FH, FM and FMX trucks (including FH4/FH, FM4/FM and FMX ranges). The valve controls air flow to downstream actuators and is electrically driven via a 24V coil. The body features multiple threaded air ports with brass inserts, an integrated electrical connector and moulded plastic housing marked "Made in GB".

The unit in the photos is the exact part you will receive. It has been removed from a fully operational truck and tested before dismantling to confirm correct electrical operation and air switching with no major leaks. After removal, it was inspected, lightly cleaned and checked for damage. There are normal signs of use such as dust, slight oxidation around the brass ports and minor cosmetic marks, but no cracks, broken connectors or stripped threads.

Installation notes:
Direct replacement for the original valve – match the OE number 21472978 (or its superseding numbers) stamped on your existing part. Professional installation is strongly recommended, as the valve is part of the vehicle pneumatic/braking system and must be fitted with clean air lines, correct sealing rings and tightened to manufacturer torque values. After installation, the system should be leak-tested and checked for proper operation; no special programming is normally required, but follow Volvo workshop procedures for your specific model.

This used original valve is ideal for cost-effective repair of Volvo FH/FM/FMХ trucks where the existing valve has failed electrically or is leaking. Always check part numbers and connector/port layout against your old unit to ensure compatibility.
