303.02.0110 4-circuit protection valve — IVECO

The heavy duty performance of your braking system depends on precision components like this 4-circuit protection valve. Designed to manage pneumatic distribution across multiple circuits, this part ensures stable air pressure and safety during operation in heavy commercial vehicle environments.

303.02.0110 is the OE-equivalent of the WABCO 934 702 380 0 used in DAF, IVECO, NISSAN UD TRUCK, and RENAULT TRUCKS vehicles. This high-strength component is also compatible with systems from IRISBUS, OTOKAR, VAN HOOL, and VDL. It serves as a critical safety element in complex pneumatic braking architectures.

For workshop technicians, this valve features specific port dimensions including a primary M22x1,5 port and four M16x1,5 auxiliary ports. It operates with an opening pressure of 7 BAR and a closing pressure of 5 BAR across all circuits to maintain system integrity. Regular inspections of the seals and port connections are recommended during routine maintenance to ensure optimal pneumatic response.

This component is engineered for durability in demanding service environments, ensuring that the air distribution remains consistent even under heavy loads. It is a vital part for maintaining the safety standards required for heavy-duty transport applications.
