The WABCO 434 014 000 0 non-return valve is a genuine OE-quality pneumatic component for compatible Faymonville trailer and commercial vehicle air systems.
The valve permits airflow in one direction while preventing compressed air from returning through the supply line. This helps maintain circuit pressure and isolates connected pneumatic equipment when the upstream pressure falls.
