Product Overview
The Rexroth DR 6 DP2-54/210YM (Material Number R900455316) is a direct-operated pressure reducing valve designed for precise secondary circuit pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve belongs to the proven DR 6 series and maintains a constant reduced outlet pressure regardless of fluctuations in the primary (inlet) pressure or changes in flow demand. The valve operates on a spool-and-spring principle: the adjustment element sets the spring preload, and the control spool modulates to throttle the inlet flow, holding the outlet pressure at the set value. When the outlet pressure exceeds the setpoint, the spool shifts to relieve excess pressure to the tank port, providing integrated pressure limitation. This makes the DR 6 DP2-54/210YM a reliable, compact solution for protecting downstream components and ensuring stable actuator performance in demanding industrial circuits.
