Product Overview
The Rexroth Z3DR 10 VP2-30/50YLG24K31/A1M (Material Number R900953085) is a high-performance, pilot-operated 3-way proportional pressure reducing valve manufactured by Bosch Rexroth. Engineered within the Z3DR series, this valve functions as a direct-operated, proportional pressure control component designed to reduce and regulate system pressure in hydraulic circuits with exceptional precision. The “3-way” spool design enables simultaneous control of both the inlet (P) and outlet (A) ports, allowing for rapid pressure relief and precise pressure modulation during dynamic load changes. The integrated proportional solenoid (designated by the “G24” code, indicating a 24 VDC supply) provides infinitely variable pressure adjustment proportional to the electrical command signal, making it ideal for applications requiring smooth, stepless pressure transitions. With a nominal size of NG10 (CETOP 5 / ISO 4401-05) and a maximum operating pressure of 315 bar, this valve is a critical control element in demanding industrial hydraulic systems where accurate pressure regulation, fast response, and high repeatability are essential.
