Description

What does a multi-circuit protection valve do?

This multi-circuit protection valve plays a vital role in the pneumatic brake system of heavy commercial vehicles by managing air pressure distribution across different circuits. It ensures that a failure in one circuit does not compromise the entire braking capability, maintaining high-strength component integrity during operation.

Compatible vehicles and engines

This component is designed for use in Mercedes-Benz vehicles. It is specifically engineered to meet the rigorous demands of heavy commercial vehicle braking requirements, providing reliable pressure control and circuit isolation.

Technical specifications and ports

The unit features several specialized ports, including M22x1.5 and M12x1.5 connections, to facilitate precise integration into existing pneumatic lines. Technical parameters include opening pressures of 7.5 BAR for ports 23/24 and 9 BAR for ports 21/22, alongside specific closing pressures ranging from 4.5 BAR to 9 BAR to maintain system stability.

Maintenance and installation guidance

For workshop technicians and fleet managers, regular inspection of the valve's ports and pressure regulation accuracy is essential for maintaining optimal braking performance. Ensure all connections are secure to prevent pressure drops within the braking circuit.
