Bendix Brakes 5003365X Relay Valve for Air Brake Systems

The Bendix 5003365X Relay Valve is a critical air brake system component designed to control and distribute compressed air to brake chambers in heavy-duty commercial vehicles. This relay valve responds to control signals from the brake application valve, providing quick and proportional air pressure delivery to the service brakes.

Key Features:

• Enables rapid brake application and release for improved response time
• Reduces lag time by delivering air from a reservoir closer to the brake chambers
• Proportional control provides smooth, modulated braking action
• Durable construction engineered for demanding commercial vehicle applications
• Designed to meet FMVSS 121 air brake system requirements

Relay valves are essential for proper air brake system operation, particularly on tandem axle configurations and trailer applications. The valve acts as a remote-controlled valve that multiplies the air signal from the treadle valve, ensuring consistent brake force across all axles. Bendix is a trusted name in commercial vehicle braking systems, known for quality and reliability in heavy-duty applications.
