Product Overview
The Rexroth DR6DP2-5X/315YM (Material No. R900592501) is a direct-operated, pilot-assisted pressure reducing valve from the proven DR6 series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the primary supply pressure or changes in flow demand. As a member of the Rexroth 5X series (component series 50 to 59), this valve is engineered for panel or manifold mounting in industrial hydraulic power units and is widely specified as a drop-in replacement for OEM installations. The valve operates on a balanced spool principle: the secondary pressure acts against an adjustable spring force, and the spool modulates to throttle the inlet flow, holding the reduced pressure steady at the outlet port. The “315” designation indicates a maximum secondary pressure setting of 315 bar, while the “YM” suffix denotes the specific adjustment and sealing configuration. This pressure control valve is a critical element in circuits requiring a stable, lower-pressure branch — such as clamping, pilot, or control circuits — fed from a higher-pressure main system.
