Description

What does a protection valve repair kit do?

This repair kit serves as a comprehensive overhaul set containing essential wear parts such as seals, diaphragms, and springs. It is specifically engineered to renew the internal components of a four-circuit protection valve within the pneumatic brake system of heavy commercial vehicles. By utilizing this kit, technicians can restore the valve to its required pressure values and response speed without replacing the entire housing.

Compatible vehicles and engines

This component is compatible with Mercedes-Benz and MAN vehicles. It ensures that compressed air is correctly distributed to the front axle, rear axle, and auxiliary consumers. If a leak occurs in one circuit, the valve protects the remaining circuits to allow the vehicle to reach a safe stop.

Installation and maintenance guidance

For optimal performance, workshop technicians should inspect the valve during regular brake system maintenance. Replacing wear parts prevents pressure drops and ensures all circuits build pressure in a balanced manner. Always verify compatibility with the existing valve housing before installation to ensure a precise fitment.

System reliability and safety

Maintaining the integrity of the pneumatic system through high-strength components helps minimize vehicle downtime and enhances overall braking safety.

OE cross-reference

303.02.0010.04 (4-Circuit Protection Valve Repair Kit) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number II14296008.

FAQ

What is included in this repair kit?
The kit typically contains essential wear parts such as seals, diaphragms, and springs required to overhaul the internal mechanism of a protection valve.
Can this be used on Mercedes-Benz or MAN trucks?
Yes, this kit is designed for use in heavy commercial vehicles from manufacturers like Mercedes-Benz and MAN to maintain pneumatic brake integrity.
How does a 4-circuit protection valve function?
It distributes compressed air into four independent circuits, ensuring that if one circuit fails, the others remain pressurized for safe braking.
When should the repair kit be used?
It should be used when signs of pressure loss or slow response times are detected in the pneumatic brake system during routine inspections.
What are the OE reference numbers of this part?
303.02.0010.04 directly replaces Knorr-Bremse OE number II14296008.
