Product Overview
The Rexroth DR20-5-5X/315Y (Material No. R900597048) is a pilot-operated pressure reducing valve from the proven DR series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the primary supply pressure or changes in flow demand. This valve belongs to the 5X series (size 20 / NG20) and is set to a nominal secondary pressure of 315 bar, as indicated by the “315Y” designation. It operates on a balanced spool principle with a pilot stage, delivering precise pressure regulation for downstream circuits that require a stable, lower working pressure than the main system supply. The DR20-5-5X/315Y is a direct-fit industrial component widely used in demanding hydraulic systems where reliable pressure control is essential for process accuracy and equipment protection.
