Description
What does a 4-circuit protection valve do?
This 4-circuit protection valve serves as a critical component within pneumatic brake systems, specifically designed to manage air pressure distribution across multiple circuits. By isolating different parts of the braking system, it prevents a leak in one circuit from compromising the entire system's integrity. Built with high-strength components, it ensures reliable performance under heavy-duty operating conditions.Technical specifications and pressure regulation
The valve is compatible with various heavy commercial vehicle braking configurations. It features specific opening pressures, including 8 BAR for ports 21 and 22, and approximately 8.1 to 8.3 BAR for ports 23 and 24, while maintaining a consistent closing pressure of 5.5 BAR across all outlets. This precision allows for stable pressure regulation throughout the air brake network.Installation and maintenance guidance
For proper installation, technicians should ensure all M22x1,5 and M16x1,5 connections are tightened according to technical standards to prevent leaks. It is essential to verify that the operating pressure remains within the maximum limit of 20 BAR during system testing to maintain optimal performance and safety.System reliability and safety
Regular inspection of the valve's port integrity and pressure response is recommended during routine maintenance intervals to ensure the continuous safety of the vehicle's braking performance.Technical Specifications
