            DESCRIPTION                                          APPLICATION
            Direct operated pressure reducing valve in screw-in cartridge   The integrated pressure relief makes an additional pressure relief
            construction  for  cavity  according  to  Wandfluh  standard.  The   valve  in  the  consumer  line  superfluous.  In  the  case  of  several
            valve reduces the input pressure to an adjustable output pres-  consumers, the pressure of the specific consumers can be indivi-
            sure. Through the integrated pressure relief function, exceeding   dually adjusted by the pressure reducing valve. Pressure reducing
            the reduced pressure as a result of external forces is avoided.   valves are used  to maintain the pressure in a consumer constant
            The  pressure reducing valve controls the pressure in port A (1).   independent  of  pressure  fluctuations  on  the  supply  side.    The
            Through increasing the spring tension, the pressure in port A(1)   screw-in cartridge is perfectly suitable for installation in control
