The Bosch Rexroth DBW 20 BG2-5X/315-6EG12N9K4 (R978911857) is a sophisticated pressure relief valve designed for precise control and safety in hydraulic systems. This pilot-operated valve serves to limit and unload operating pressure through solenoid activation. It features 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. This model's functionality mirrors that of the DB type valves, but it distinguishes itself by unloading the main spool via the mounted directional spool valve. The DBW 20 BG2-5X/315-6EG12N9K4 is equipped with switching shock damping capabilities, which provide a sandwich plate version for dampening decompression shocks and minimizing pressure peaks. This is achieved by delaying the opening from port B to B, ensuring smoother operation and reducing noise in the system. The effectiveness of this shock damping is influenced by the size of the nozzle; for this particular model, a nozzle with an ordering code R is recommended. Designed for subplate mounting, it adheres to ISO standards NG6, NG10, and NG16 for porting patterns. It can also be utilized as a screw-in cartridge valve. Users have several options for setting and adjusting pressure levels including rotary knobs, sleeves with hexagons and protective caps, lockable rotary knobs with scales, or simple rotary knobs with scales. The maximum operating pressure capacity reaches up to 315 bar while handling maximum flow rates up to specified limits depending on the series. Additionally, this model supports high-power solenoid operation for unloading via built-on directional spool valves or directional poppet valves. The option for switching shock damping adds versatility to its application in various hydraulic circuits requiring precise pressure management.
