Abstract
A pressure relief valve system is provided that makes it possible to provide numerous varied pressure relief functions with a minimum of structural changes. For this purpose, a standard distributing valve housing is equipped with a valve core that makes it possible to construct a double-acting pressure relief valve with an individually adjustable pressure system on each valve side. However, there is also the possibility of completely shutting off the pressure system on one side. The valve core and/or the valve elements are preferably exchangeable, and the valve elements can be separately controlled by an adjusting device, for example in the form of a proportional magnet, to generate a pressure output signal corresponding to an input signal in each of the independent pressure systems independent of one another.
