High-Performance Brake System Relay Valve for King Long, Higer & Ankai Buses | P/N: 3527-00042 / 9730110010
Product Description
Ensure Instantaneous Braking Response and Maximum Safety.
In the pneumatic braking system of a heavy bus, response time is a critical safety factor. The Relay Valve, manufactured by Nanjing Dingguan Accessories Co., Ltd., is an essential component designed to dramatically reduce brake lag, ensuring your fleet has the stopping power it needs, precisely when it’s needed.
This valve acts as a pneumatic amplifier. It receives a small air pressure signal from the driver’s brake pedal and instantly directs a large volume of air from a local reservoir to the brake chambers. This process significantly speeds up the application and release of the brakes, especially on the rear axles, ensuring rapid, powerful, and balanced braking across the entire vehicle.
Key Features:
- Faster Brake Response: Drastically reduces brake system lag time, leading to shorter stopping distances and improved emergency braking performance.
- Broad Fleet Compatibility: Engineered as a high-quality replacement for China’s leading bus manufacturers, including King Long, Higer, and Ankai.
- Direct OEM Replacement: Perfectly cross-referenced for part number 3527-00042 and the globally recognized WABCO standard 9730110010, guaranteeing a seamless fit and function.
- Durable and Reliable: Constructed from high-grade, corrosion-resistant materials to withstand the rigors of the pneumatic system and ensure a long, dependable service life.
As a direct manufacturer, we deliver superior quality and value. Do not compromise on the single most important safety system of your vehicles.
