Product Overview
The Rexroth 3DR16P5-53/100Y/00M (Material Number: R900916666) is a high-performance 3-way pressure reducing valve from the proven Rexroth 3DR series, engineered for precise downstream pressure regulation in demanding industrial hydraulic systems. Operating on a direct-operated, spring-loaded poppet/spool principle, this valve continuously senses outlet pressure and modulates flow to maintain a stable reduced pressure regardless of fluctuations in inlet pressure or system flow demand. The 3-way design enables both pressure reduction and pressure relief (return flow to tank) when outlet pressure exceeds the set value, making it ideal for circuits requiring bidirectional pressure control. With a nominal size of NG16 and a pressure rating of 100 bar, this valve is a direct-fit replacement for OEM installations and is widely deployed in plastic injection molding machines, metallurgical presses, and precision machine tool hydraulics.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated 3-way spool design delivers accurate, repeatable downstream pressure control with minimal hysteresis, ensuring consistent actuator performance across varying load conditions.
- 3-Way Pressure Relief Function: Unlike 2-way reducers, this valve actively relieves excess downstream pressure back to tank, preventing pressure spikes and protecting sensitive components in the secondary circuit.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust housing, hardened spool, and precision-machined bore for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, including the R900916666 material number, ensuring drop-in installation without modification.
- Stable Performance Under Flow Variation: Compensated spool geometry maintains set pressure even as system flow demand changes, critical for multi-actuator circuits.
