Product Overview
The Rexroth DR20-5-5X/200YM (Material No. R900597233) 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 (inlet) pressure or changes in flow demand. As a normally open, three-way pressure reducing valve, it limits the pressure in a secondary circuit to a preset value while simultaneously providing a return path to tank when downstream pressure rises above the set point. The “200” designation indicates a pressure adjustment range up to 200 bar, while the “YM” suffix denotes the specific adjustment and control configuration. This valve is engineered for panel or manifold mounting in demanding industrial hydraulic power units and is fully interchangeable with original Rexroth OEM specifications.
