Stufenlos verstellbares Proportionalventil für Dämpfkraft

Control valve Chassis damping

This intelligent valve technology describes the premier class of infinitely variable proportional valves: optimization of adaptive suspension damping in semi-active suspensions.

Control of the damping force, infinitely variable. Enables damping force adjustment according to the skyhook principle.

Pressure retention valve

The pressure retention valve is installed as an integral part in air suspension struts. In the event of a defect – e.g. in the event of a hose rupture between the air suspension strut and the air compressor – the PRV closes automatically and thus prevents the air suspension strut from being damaged or destroyed.

Variable valve block sensor cleaning

A valve block consists of three electromagnetic switching valves for precise fluid control in sensor cleaning systems.

Thanks to special, highly developed intelligent valve technology, controlled dosing and pressure control of the liquid is ensured as required. This also minimizes the consumption of cleaning fluid and still achieves optimum cleaning results.
