4425013400 Levelling Valve for SAF Systems

What does a levelling valve do?

This levelling valve plays a critical role in maintaining the correct ride height of air-suspended heavy commercial vehicles. By regulating air pressure within the suspension system, it ensures the vehicle remains stable and level under varying load conditions.

Vehicle and system compatibility

Designed for use in heavy-duty applications, this component is compatible with SAF systems. It is engineered using high-strength components to withstand the rigorous demands of constant movement and pressure changes inherent in commercial transport.

Technical specifications

The technical configuration includes M12x1.5 ports (Port 1, Port 2, Port 21, Port 22) and one M16x1.5 port (Port 23). It operates at a maximum pressure of 13 bar and features a lever diameter range of Ø 6 to 315 mm for precise adjustment.

Maintenance and installation guidance

To ensure optimal performance, technicians should inspect the lever movement and port integrity during routine maintenance. Maintaining correct operating pressure is essential for preventing uneven wear on the suspension bellows and ensuring stable vehicle handling.

OE cross-reference

303.07.0002 (Levelling Valve) is the equivalent of the SAF OE number. This part directly replaces SAF OE number 4425013400.
