• Fit for: Meritor
  
• Functions:
  
  • Redundancy: The valve provides a redundant safety feature by ensuring that the emergency brakes can be activated even if the service brake system fails. This helps to prevent accidents and protect the lives of drivers and passengers.
    
  • Emergency braking: If the service brake system fails or loses pressure, the valve opens automatically, allowing air to flow from the service brake reservoir to the emergency brake reservoir. This activates the emergency brakes, bringing the vehicle to a safe stop.
    
  • Normal operation: Under normal driving conditions, the valve remains closed, preventing air from flowing from the service brake reservoir to the emergency brake reservoir. This ensures that the emergency brakes are only activated in the event of a failure in the service brake system.
