How many dump valves do the articulated buses have?

Articulated buses typically have four dump valves to manage the air suspension system effectively. These valves are crucial for adjusting the ride height and allowing the bus to lower for easier boarding and alighting of passengers. The four dump valves are positioned to control the air distribution across the linked sections of the bus, ensuring stability and comfort while maintaining safety standards. Each valve plays a role in functioning the air suspension system, enabling the bus to adapt to different passenger loads and road conditions. Understanding this mechanism is essential for operators to ensure the bus operates smoothly and maintains the necessary clearance for efficient operation.
