Therefore, large filter areas must be installed and the use of a bypass valve and a contamination indicator is strongly recommended.<\/p>\n<\/p>\n<p><strong>Pressure filters<\/strong>are installed downstream of the pump (i.e. on the pressure side of the hydraulic pump) and have the task of protecting particularly sensitive components (e.g. proportional valves, servo valves).
