Abstrakt:	The investigation of a pilot operated proportional pressure relief valve is described in this article. Different measurements are performed with a hydraulic test bench under laboratory conditions. A VTVSPA1- 1 amplifier module is used to control the current of the valve's solenoid. The characteristics of the valve are determined as a function of the pressure -- command value of the amplifier -- volume flow rate. The results of the measurements can provide input data for the refinement of the mathematical model of the unit, which will be set up in the future. [ABSTRACT FROM AUTHOR]
