303.02.0007 4-circuit protection valve

The pneumatic control of the braking system relies heavily on the precision of the protection valve to ensure safety and reliability. This 4-circuit protection valve is engineered to maintain optimal pressure distribution across multiple circuits, providing essential stability for heavy commercial vehicle braking systems.

The 303.02.0007 is the OE equivalent of the KNORRBREMSE AE4604, VOLVO 20382309, VOLVO 20452151, VOLVO 20716313, VOLVO 20755195, and VOLVO 3197588 used in VOLVO FH12, FH13, FM12, and MACK Granite models. It operates with a maximum pressure of 20 BAR and features specific opening/closing thresholds for ports 21, 22, 23, and 24 to manage system fluctuations effectively.

Designed for professional workshop technicians, this component ensures seamless integration into existing pneumatic architectures. The technical specifications include a Port 1 size of M22x1,5 and four M16x1,5 ports (21-24) to accommodate standard industrial connections used in heavy-duty vehicle maintenance.

Regular inspection of the valve opening and closing pressures is recommended to prevent system failures. This component is an essential part for maintaining the safety standards of high-performance commercial fleets.
