DBW20B1-5X/315-6EG24N9K4 R900920619 Pressure Relief Valve of Rexroth

The Bosch Rexroth DBW20B1-5X/315-6EG24N9K4 (R900920619) is a high-performance industrial hydraulic valve designed for reliable pressure limitation and solenoid unloading via a built-on directional spool valve. This pilot-operated pressure relief valve includes a main valve with a spool insert, a pilot control valve with an adjustable pressure element, and an integrated directional spool valve, ensuring precise control over hydraulic systems. The DBW20B1-5X/315-6EG24N9K4 operates within a pressure adjustment range of up to 315 bar and is capable of handling a maximum flow rate of 150 l/min. This model features mechanical actuation and comes with an electrical connector that is compatible with a 4-pole PE according to EN 175301-803 standards, requiring a supply voltage of 24 VDC. It is designed for subplate mounting with porting patterns that comply with ISO standards NG6, NG10, and NG16. The valve's weight is approximately 3.7 kg and it uses NBR seals compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The DBW20B1-5X/315-6EG24N9K4 also offers optional features such as switching shock damping for mitigating pressure peaks and reducing acoustic decompression shocks in return lines by delaying the opening from port B to B. Users can choose from different adjustment types for pressure settings including rotary knobs or sleeves with hexagon and protective cap among others. Furthermore, this model can be ordered for threaded connection as a screw-in cartridge valve (cartridge). With its robust design and versatile capabilities, the Bosch Rexroth DBW20B1-5X/315-6EG24N9K4 serves as an essential component in advanced hydraulic systems requiring precise pressure management.
