What is the FAW Trailer Manual Valve Assembly

  • 1. FAW Trailer Manual Valve Assembly: Precision Trailer Brake Control
    This critical assembly provides the driver with direct, proportional control over the FAW truck’s trailer braking system. Mounted within the cab, the hand-operated valve regulates air pressure delivered to the trailer brakes, enabling smooth, controlled stopping of the trailer in sync with the tractor.
  • 2. Core Control Unit: Valve & Connection
  • Trailer Manual Valve With Fast Plug Connector Assembly: This is the primary operator control. The hand valve itself features an ergonomic lever for intuitive modulation. Crucially, it incorporates a Fast Plug Connector, allowing swift, secure, and leak-free connection/disconnection of the trailer’s emergency/supply line (often the red Gladhand line) to the tractor’s trailer control circuit.
  • Trailer Manual Valve Assembly: Represents the complete, functional unit ready for installation, encompassing the valve body, internal mechanism, lever, and the integrated Fast Plug Connector.
  • 3. Sealed Connection Interface
  • Threaded Sleeve (M16) With Seal Ring Assy: This vital sealed fitting provides the robust, leak-proof interface where the main air supply and delivery lines connect to the valve body. The M16 thread ensures a secure mechanical connection.
  • Special Shaped Seal Ring(Φ 9.7): A precisely engineered seal installed within the Threaded Sleeve Assy. Its unique shape (Φ 9.7mm) creates a high-integrity, pressure-tight barrier between the threaded sleeve and the valve port, preventing air leaks critical for reliable brake signal transmission.
  • Circlip(Φ 10): A retaining ring (Φ 10mm) used internally within the valve assembly or potentially on the Threaded Sleeve Assy shaft. It secures components like pistons, shafts, or seals in place, ensuring they remain positioned correctly under pressure and vibration.
  • 4. Secure Mounting Hardware
  • Assembling Bolt: High-strength bolts used to securely fasten the Trailer Manual Valve Assembly bracket to its designated mounting point within the FAW truck’s cab. This ensures the valve remains stable and accessible during operation.
