A hydraulic valve bank has at least two valve sections, a connection section, and a pressure channel for pressurizing the valve sections. The pressure channel connects the connection section to each valve section for pressurizing them. Each valve section has a spool, an electrohydraulic pilot control for actuating the spool and an upstream pressure compensator. The valve bank is a load-sensing system and has a load pressure collecting channel for signaling the highest load pressure. A common pilot pressure signal is applied to the electrohydraulic pilot control of each valve section via the connection section. A single pilot control pressure influencing valve changes the common pilot pressure signal, and is connected to the pressure channel to be acted upon in a first switching direction, and to the load pressure collecting channel to be acted upon in a second switching direction. A mobile hydraulic system includes such a hydraulic valve bank.
