Four-Circuit Protection Valve: Function and Purpose
The Four-Circuit Protection Valve is a critical component in commercial vehicle braking systems, particularly in trucks and buses. Its primary function is to ensure safety by dividing the compressed air supply into four independent circuits, preventing a total brake system failure in case of a leak or malfunction in one circuit.
Air Distribution - Splits the compressed air from the reservoir into four separate circuits (e.g., front brakes, rear brakes, parking brake, and auxiliary systems).
Pressure Protection - Maintains stable air pressure in intact circuits even if one circuit fails.
Leak Isolation - Prevents air loss in one circuit from affecting the others, ensuring partial braking capability remains.
Sequential Filling - Ensures circuits are pressurized in a specific order (e.g., primary brakes first, then secondary systems).
Safety Compliance - Meets regulatory standards (e.g., ECE R13, FMVSS 121) for redundant braking systems in heavy vehicles.
Trucks & Buses - Ensures braking reliability even with air leaks.
Trailers - Maintains brake function if one circuit fails.
Industrial Vehicles - Provides redundancy for critical air brake systems.
