Product Overview
The Rexroth ZDR 6 DP2-43/75YM (Material No. R900483786) is a direct-operated, pilot-assisted pressure reducing valve from the proven ZDR 6 series, designed to maintain a constant reduced outlet pressure regardless of fluctuations in the primary (inlet) pressure or changes in flow demand. This sandwich plate valve, built to ISO 4401 / DIN 24340 size 6 (NG6 / CETOP 3) interface standards, regulates secondary circuit pressure by means of an adjustable compression spring acting against a control spool, with a pilot stage providing precise pressure sensing and fast response. The “DP2” designation indicates a pressure reducing function with secondary pressure relief capability and a specific adjustment/connection variant, while the “75YM” code defines the pressure adjustment range and adjustment type (75 bar maximum reduced pressure setting, with a specific adjustment element). As a core pressure control component, the ZDR 6 DP2-43/75YM protects downstream actuators, clamping circuits, and sub-systems from over-pressure while delivering stable, repeatable reduced pressure for precision industrial hydraulic operations.
