• Weight: 3 lbs
• Fit for: Peterbilt - 579, Kenworth 
• Functions:
  
  • Parking brake: The valve may also be used to control the parking brake, which is applied to hold the vehicle in place when parked.
    
  • Emergency braking: In the event of a loss of air pressure, the valve is designed to activate an emergency braking system. This typically involves automatically applying the brakes to bring the vehicle to a stop.
    
  • Pressure control: The valve regulates the air pressure that is sent to the brake chambers. When the driver depresses the brake pedal, the valve opens, allowing air to flow into the brake chambers. This increases the pressure on the brake shoes, causing them to apply pressure to the brake drums or discs, slowing or stopping the vehicle.
