The Rexroth R900504902 DB30-2-52/350 is a pilot-operated pressure relief valve designed as a cartridge valve for insertion into standardized cavities according to ISO 7368. Its primary function is to limit the pressure within a hydraulic system to a predetermined maximum level. This valve features an integrated pilot control valve (version 2) and is set for a maximum pressure of 350 bar. Its pilot-operated design ensures stable pressure control across varying flow rates, making it suitable for demanding hydraulic applications requiring reliable pressure limitation.
