The Bosch Rexroth DBW 30 B2-5X/350U6EW110N9K4/12 (R978022439) is a sophisticated pilot-operated pressure relief valve designed for high-performance hydraulic systems. This valve is engineered to manage and limit operating pressure through solenoid-actuated unloading, ensuring consistent and reliable control in various applications. The DBW 30 B2-5X/350U6EW110N9K4/12 features a main valve with a spool insert and a pilot control valve that includes an adjustable pressure element, along with an integrated directional spool valve. The functionality of this model mirrors that of the DB type valves, with the added benefit that unloading of the main spool is achieved via the mounted directional spool valve. It includes a switching shock damping sandwich plate version, which helps in mitigating pressure peaks and reducing acoustic decompression shocks by delaying the opening from connection B to B. This feature is crucial for maintaining system integrity and preventing potential damage caused by sudden pressure changes. Installation versatility is a key aspect of this model as it can be mounted on a subplate with porting patterns conforming to ISO standards NG6, NG10, and NG16 or used as a screw-in cartridge valve. The pressure adjustment can be customized using various methods including rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale. This unit also supports solenoid-operated unloading via built-on directional spool valves or directional poppet valves and comes equipped with high-power solenoids for robust operation. Optional switching shock damping further enhances its performance capabilities. The maximum operating pressure for this component series X is rated at up to 350 bar, while it can handle maximum flow rates measured in liters per minute (l/min), ensuring suitability for demanding hydraulic tasks.
