Critical ABS Modulator Valve for Major Bus Fleets | Replaces WABCO 3550-00017

Product Description

The Anti-lock Braking System (ABS) is the cornerstone of active braking safety, and at its heart lies the ABS Modulator Valve. Nanjing Dingguan Auto Parts Co., Ltd. manufactures this high-performance, 24V actuator, engineered as a direct replacement for WABCO system part 3550-00017. It is the trusted solution for a wide range of bus fleets, including Yutong, King Long, Zhongtong, and Ankai.

This valve's function is non-negotiable. It receives high-speed commands from the ABS ECU and, in milliseconds, precisely modulates air pressure to the brake chambers. This action prevents wheel lock-up during emergency braking, allowing the driver to maintain steering control and significantly reducing stopping distances. A faulty modulator compromises this entire safety net.

Key Features & Benefits:

• Critical Safety Restoration: Restores the full, instantaneous functionality of the ABS, ensuring the vehicle remains stable and steerable under heavy braking.
• Wide Fleet Compatibility: A single, reliable solution for major Chinese bus brands equipped with 24V WABCO-type ABS systems, simplifying inventory for mixed fleets.
• Rapid & Precise Response: Features high-speed internal solenoid valves for the instantaneous pressure release and re-application required for effective anti-lock control.
• Built for Durability: Constructed with a robust housing and sealed electrical connectors to protect against moisture, road grime, and vibration, guaranteeing a long and reliable service life.

As a specialized manufacturer, Nanjing Dingguan is committed to providing safety-critical components you can depend on.
