The WABCO 12V 2-delivery port trailer ABS relay valve kit is designed to enhance braking stability for trailers. It features a quick-response mechanism that improves safety during emergency stops. By separating brake actuation from pressure delivery, it allows for efficient control. It also minimizes trailer sway through precise pressure regulation, making it particularly suitable for heavy duty applications. With two delivery ports, it offers a reliable braking solution for applications requiring stability and improved performance during braking actions.
