What is the FAW Trailer Valve Port Assembly

  • 1. FAW Trailer Valve Port Assembly: Core Trailer Brake Control Interface
    This critical assembly integrates the primary valve and sealed connection ports managing compressed air flow between the FAW tractor and its trailer. Mounted on the chassis, it ensures precise modulation and reliable delivery of brake signals and supply air to the trailer’s braking system, forming the essential control point for safe towing operations.
  • 2. Central Control Valve & Quick Connection
  • Trailer Valve With Fast Plug Connector Assy: The heart of the assembly. This valve (often a relay or control valve) regulates trailer brake application pressure based on tractor inputs. Its integrated Fast Plug Connector enables swift, secure, and leak-free attachment of the trailer’s emergency/supply line (typically the red Gladhand).
  • Trailer Valve Port Assy: Represents the complete functional unit, combining the valve body, internal mechanism, and the essential port interfaces ready for installation.
  • 3. High-Pressure Sealed Port Interfaces
  • Threaded Sleeve (M16) With Seal Ring Assy: Provides a robust, leak-proof connection point for smaller control signal lines or auxiliary ports (M16 thread).
  • Threaded Sleeve (M22) With Seal Ring Assy: Delivers a robust, leak-proof connection point for main supply/service air lines handling higher flow rates (M22 thread).
  • Special Shaped Seal Ring(Φ 9.7): Precision seal within the M16 sleeve, creating a vital pressure-tight barrier.
  • Special Shaped Seal Ring(Φ 15.2): Precision seal within the M22 sleeve, ensuring integrity under higher pressures and flows.
  • 4. Internal Component Security
  • Circlip(Φ 10) / Circlip(Φ 12): Internal retaining rings securing critical valve components like pistons, shafts, or seals within the Trailer Valve Assy under system pressure and operational vibration, preventing internal failure.
  • 5. Robust Chassis Mounting
  • Bracket Of Trailer Valve: A heavy-duty, vehicle-specific bracket providing a rigid and vibration-resistant mounting platform on the FAW tractor chassis, ensuring stable valve positioning and alignment with air lines.
  • Hexagon Flange Bolt Thick Rod (Standard Type): High-strength bolts with thick shank and integrated flange. Used to securely fasten the Bracket Of Trailer Valve to the chassis, offering exceptional shear strength and load distribution crucial for this safety-critical component.
  • Hexagon Flange Lock Nut: Paired with the thick rod flange bolts, these nuts feature integrated locking elements to prevent loosening under constant vibration.
  • Hexagon Flange Nut: Standard flange nuts used for securing the valve assembly itself to its bracket, providing good load spreading.
