Description Size 3 Component series A Max. operating pressure 350 bar Flow, max. 200 l/min Features Cartridge valve Mounting cavity R/ISO 7789-33-01-0-98 Pilot-operated proportional valve for system pressure limitation Suitable for mobile and industrial applications Actuation by proportional solenoid with central thread and detachable coil Fine adjustment of the command value pressure characteristic curve possible from the outside at the control electronics In case of power failure, the minimum pressure is set Product description Type KBVS valves are pilot-operated proportional pressure relief valves in seat design and are used for limiting the pressure in hydraulic systems. They mainly consist of the screwed in proportional pilot control valve and the main valve. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. With a command value of 0 or in case of power failure, the minimum pressure is set.

The maximum operating pressure is added up from the set pressure and the return flow pressure. 2) The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the
