Coolant Inline Valves
With its innovative valve technology, Pierburg's inline valve enables optimum connection in terms of installation space by eliminating the usual axial offset between the input and output lines. Because the actuator is located in line with the coolant ports, this enables much more compact packaging in the vehicle. The lowest pressure losses of the Pierburg inline valve allow reduced power consumption of the volumetric pump as well as a significantly increased throughput. The patented valve design reduces pumping effects and thus minimizes switching noises.
