Purpose and Function in the Vehicle System

The described relay valve acts as a central control element in the body or axle lifting system for DAF 85CF tractors and chassis. It is responsible for precisely transmitting control signals to the actuators, which translates into smooth operation of the lifting mechanism and predictable system responses under various load conditions.

Thanks to the design developed by the vehicle manufacturer, the valve is optimized for seamless integration with the factory pneumatic and control systems, facilitating diagnostics and reducing the risk of malfunctions in the entire system. This is particularly important for vehicles used in long-haul and distribution transport, where consistent performance and minimized service downtime are crucial.

Benefits of Using an Original DAF Component

Using an original DAF solution for the trailer lifter and body lifting system helps maintain operational parameters consistent with the manufacturer's original specifications. The appropriate flow and control characteristics contribute to:

• stable operation of the lifting system under typical road conditions,
• improved repeatability of responses to signals from the driver's cabin,
• easier integration with the existing pneumatic and electrical installation,
• reduced risk of incompatibility with other control components.

For workshops and fleet operators, this means simpler selection of replacement parts, predictable installation, and the ability to utilize standard service procedures applied to DAF vehicles.

Operational Characteristics and Condition

This element belongs to the control group and is offered as a used part, allowing for economical system repair while maintaining the manufacturer's original design. Such components are often chosen when compliance with the factory system and minimizing vehicle downtime costs are paramount.

In workshop practice, relay valves used in body lifting systems are subjected to intensive use, so selecting the correct model directly impacts the reliability of the entire system. By choosing an original element from this group, you minimize the risk of compatibility issues and the need for installation modifications.

Selection, Compatibility, and Service Application

When selecting a relay valve for the trailer lifter system in a DAF 85CF, it is crucial to match it to the specific vehicle configuration and existing control system. The offered element has an assigned OEM part number and interchangeable numbers, which simplifies verification of compliance with service documentation and manufacturer catalogs, without requiring modifications to the system's design.

This solution is particularly beneficial for fleet service centers, where component consistency, quick part identification, and reduced diagnostic time are important. Using the correct relay valve in the body lifting system contributes to vehicle operational safety during loading and unloading, as well as driver comfort.
