The Bosch Rexroth DBW20A2-5X/315-6EW110N9DK25LSO160 (R900927705) is a highly sophisticated pressure relief valve designed for advanced hydraulic systems. This pilot-operated valve is engineered to limit and control the unloading of operating pressure through solenoid actuation. It integrates a main valve with a spool insert and a pilot control valve that includes a pressure adjustment element, along with an integrated directional spool valve. The DBW20A2-5X/315-6EW110N9DK25LSO160 stands out for its switching shock damping feature, which is vital for reducing pressure peaks and acoustic decompression shocks in return lines, thereby enhancing system stability and longevity. The damping effect is achieved by delaying the opening between connections B to B using a switching shock damping valve situated between the pilot control valve and the directional valve. The extent of shock damping can be customized based on the nozzle size used, with the recommended size being denoted by ordering code R. This Bosch Rexroth pressure relief valve is versatile in its mounting options, suitable for subplate mounting with porting patterns that comply with ISO NG standards. It can also be utilized as a screw-in cartridge valve for threaded connections. Users have several adjustment types to choose from for precise pressure setting, including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or simply a rotary knob with scale. The model features solenoid-operated unloading either via built-on directional spool valves or directional poppet valves equipped with high-power solenoids. Its design caters to different pressure ratings and offers optional switching shock damping to cater to various application needs in hydraulic systems where controlled pressure relief is critical.
