Description

The heavy duty Load Unloading Valve is a precision-engineered component designed to manage air pressure transitions within the brake system. Utilizing high-strength components, this part ensures reliable operation under demanding heavy commercial vehicle conditions. The 180° lever position and specific pressure adjustment ranges make it an essential part for maintaining system stability.

303.09.0004 is the OE equivalent of the WABCO 475 604 013 0 Load Unloading Valve used in SCANIA, DAF, and JOHN DEERE vehicles. This component is also compatible with systems from FRUEHAUF (CF350516/TSH6051-1), TEREX (34654440), and VAN HOOL (637204200, 637205430).

For workshop technicians, this valve features dual M22x1,5 ports to ensure standard assembly and secure connection. It is critical to verify the adjustment range—Empty Pressure (1,4 - 2,8 BAR) and Half Pressure (3,4 - 4,3 BAR)—during installation to ensure optimal pneumatic performance and system-wide compatibility.
