Safety, stability and reliability are the most important demands on a braking system. But a system is only ever as good as its weakest link. Direct operated, proportional pressure reducing cartridges from Wandfluh with fast response times and very low leakage can be used for a variety of purposes. One typical application is in hydraulic braking systems, which require a fast build-up of pressure, good reproducibility and linearity. With a worldwide use, reliable operation, even in extreme conditions, has to be ensured. The use of special materials, increased corrosion and explosion protection help to withstand extreme cold, heat or the influence of salt water, gas and dust. The new models from Wandfluh are available in two sizes with different cavities and maximum flow.The smaller execution of the MDPPM16 and MGPPM16 series has been designed for a maximum flow of 6 l/min. The cartridge body has a M16x1.5 thread. Through these small dimensions, the requirements of numerous users with respect to a compact, space-saving design are satisfied. As a standard, three pressure levels, 25, 40 and 100 bar are available for the reduced pressure.With the larger models in the MPPPU10 series, a maximum flow of 20 l/min can be achieved. The cartridge body has a 7/8''-14 UNF cavity.For both sizes the inlet pressure is 350 bar.To control the proportional solenoids, Wandfluh offers a variety of digital amplifiers and control electronics. For use in potentially explosive areas, the valves can be equipped with the proven MKY coil (protection class Exd).
