Product Overview
The Rexroth DR 10 G5-45/200YM (Material No. R900413544) is a direct-operated pressure reducing valve from the proven Rexroth DR 10 series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the inlet pressure or changes in flow demand. The valve is a pilot-assisted, spring-loaded poppet-type pressure reducer in a size 10 (NG10) sandwich and subplate mounting configuration. The “G5” designation indicates the adjustment element type (rotary knob with hexagon socket and lock nut), while “45” denotes the standard pressure adjustment range and “200YM” specifies the reduced pressure setting of 200 bar with a specific spring and seal configuration. This valve is a critical pressure control component in industrial hydraulic systems, protecting downstream actuators, cylinders, and sensitive circuit branches from overpressure while delivering a stable secondary pressure.
