The WABCO Pressure Controlled Check Valve directs airflow within pneumatic circuits based on internal pressure conditions. When system pressure rises to its operating threshold, the valve opens to permit air movement while restricting reverse flow paths. This behavior helps coordinate air charging across connected lines without manual input. Internal components respond automatically as pressure fluctuates during normal operation. Air routing changes occur only when system conditions require it. The WABCO 4341003100 supports controlled airflow behavior within pressurized braking and auxiliary air systems.
