Rexroth has introduced a new size to its range of modular directional valves that is rated at up to 25ltrs/min with working pressures of up to 310bar. The valves are designed to cope with the harsh working environments inherent in mobile machines. Rexroth’s comprehensive range of modular directional valves now covers workflows of up to 50ltrs/min. Although based on NG4/NG6 technology, the valves avoid sub-plates and can be tailored to specific workflow requirements. System modularity allows for the number of sections to be expanded by the end user in the event of more functions being required for the machine. Individual sections come in different size options with one common interface; this ensures cost-effectiveness, since the engineer can choose the appropriate size per section according to the required flow. 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.
