Multi-Circuit Independent Security: The valve effectively splits the compressed air into four distinct circuits (front axle, rear axle, parking brake, and auxiliary equipment). If a leak occurs in one circuit, the valve automatically isolates it to prevent a total loss of air pressure.
Precision Pressure Regulation: Features high-quality internal diaphragm and spring sets that ensure accurate opening and closing pressures, maintaining the Brake System stability even under extreme heavy-load conditions.
Robust Aluminum Construction: Manufactured using high-strength die-cast aluminum alloy, providing excellent resistance to oxidation, thermal expansion, and mechanical vibration.
Integrated Check Valve Function: Each circuit includes an internal check valve mechanism that prevents backflow, ensuring that the remaining intact circuits can still provide enough braking force for emergency stops.
Primary Vehicle Fitment: Specifically designed for heavy-duty trucks utilizing MAN Technology chassis, most notably the Shacman Delong F3000, X3000, and M3000 series.
System Integration: Installed immediately after the air dryer in the pneumatic layout to serve as the "brain" for air distribution within the Truck Air Brake System.
Operating Conditions: Suitable for long-haul logistics vehicles, mining dump trucks, and construction machinery where consistent air pressure is vital for safety.
Air Dryer Assembly (Model: DZ95259360010): Prevents moisture from entering the four-circuit valve to avoid internal freezing or corrosion.
Relay Valve (Model: DZ9100360050): Works in conjunction with the protection valve to accelerate the inflation and deflation of the brake chambers.
Brake Chamber (Model: DZ9100360002): The final actuator that receives the air pressure regulated by the protection valve.
Air Tank / Reservoir: Stores the pressurized air distributed by the 4-way valve for different circuits.
