Rexroth has added a new size to its range of modular directional valves that is rated at up to 25 litres/min and for working pressures of up to 310bar. The compact valves are able to cope with the harsh working environments inherent in mobile machines. Rexroth’s modular directional valve range now covers workflows of up to 50 litres/min. Although based on NG4/NG6 technology, the valves avoid sub-plates and can be tailored to specific workflow requirements, especially when compared to standard CETOP (Comite Europeen des Transmissions Oleohydrauliques et Pneumatiques) solutions. The modularity of the system allows for the number of sections to be expanded by the end user if more functions are required of the machine. The individual sections come in different size options with one common interface. Furthermore, the modular valve design provides for sections with integrated load sensing, as well as other integrated functions such as check valves, relief valves, counterbalance valves, flow regulators, emergency hand levers and emergency hand pumps. In addition, this line of sectional valves can be connected to Rexroth power modules and integrated control blocks with cartridges and other valves to create hybrid systems.
