The present invention aims at providing a new electro-hydraulic control terminal adopting modularized and configured cartridge valve RHCV. It has obvious advantages of hybrid combination and flexible customization when RHCV is applied in the independent control terminals based on “single loop resistance” to control hydraulic actuators including distributed cylinders and motors. It can follow the rules that functional diversities as many as possible can be achieved through technical diversities as few as possible, thus producing a new generation of electro-hydraulic product family and platform to meet the needs of customers.

Techniques involve a hydraulic valve module having at least one hydraulic valve with a valve slide which can be adjusted by way of an electric actuator in order to supply hydraulic lines with hydraulic liquid by way of the hydraulic valve. The hydraulic valve module has a controller and an electric energy store. The controller and the electric energy store are set up to move the valve slide out of every possible valve slide position into a deactivation position by way of the electric actuator and energy which is stored in the electric energy store. This allows the safe operation of hydraulic valves without a restoring spring, wherein valves of this type and the actuators thereof can be of smaller and less expensive construction than in the case of conventional valves with a restoring spring.
