Product Overview
The Rexroth Z3DREE 10 VP2-10/315LG24K31A1M (Material No. R901551390) is a pilot-operated, three-way proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As part of the Rexroth Z3DREE series, this valve reduces a primary system pressure to a regulated secondary pressure that is proportional to the electrical command signal applied to its integrated proportional solenoid. The valve features a 3-way spool design (pressure reducing and relieving function), enabling it to both increase and decrease the outlet pressure in response to command signal changes, ensuring stable and accurate pressure regulation even under varying load conditions. With a nominal size of NG10 (Size 10) and a maximum inlet pressure rating of 315 bar, this valve is engineered for demanding applications requiring high-resolution pressure control, fast response, and excellent repeatability. The integrated control electronics (type “K31A1M”) provide factory-calibrated, closed-loop pressure regulation, simplifying system integration and eliminating the need for external amplifier cards. This valve is a direct-fit, OEM-compatible component suitable for new installations and drop-in replacements in existing Rexroth hydraulic systems.
