Description
The 4-circuit protection valve is a critical component within the brake system designed to maintain pneumatic stability across multiple circuits. This component ensures that pressure-sensitive operations remain consistent even during rapid changes in system demand. High-strength components are utilized to ensure long-term reliability in demanding environments.
The 303.02.0033 is the OE equivalent of the SCANIA 1356635 and is also compatible with several other high-profile systems including DAF 1505406, MAN ZG046460002, ProVia PRO1220030, and WABCO 9347142110. It serves a vital role in maintaining the integrity of the pneumatic circuit for brands such as Alexander Dennis, Scania, and VDL.
For workshop technicians performing maintenance or system overhauls, this valve provides precise pressure control with specific opening pressures of 6,5 BAR and 7,4 BAR across its ports. The technical specifications include specialized port sizes like M22x1,5 and M16x1,5 to ensure a secure fitment during installation.
Regular inspection of the braking system components can prevent unexpected downtime in heavy commercial vehicles. Always verify compatibility with the specific vehicle model and existing pneumatic hardware before installation.
