Product Overview
The Rexroth ZDR 6 DP0-45/40 YM W80 (Material Number: R900323180) is a direct-operated, three-way pressure reducing valve from the proven Rexroth ZDR 6 series. Designed for subplate mounting in accordance with ISO 4401 / DIN 24340, this valve maintains a constant reduced outlet pressure regardless of fluctuations in the inlet pressure or changes in flow demand. The “DP” designation indicates a three-way pressure reducing function, which allows excess downstream pressure to be relieved to the tank port, making it ideal for circuits requiring precise secondary pressure control. The valve features a robust housing, a hardened and ground control spool, and an adjustable pressure setting mechanism, ensuring stable and repeatable performance in demanding industrial hydraulic systems.

Engineering Features & Advantages
- Precise Pressure Regulation: The three-way design (ZDR) provides accurate and stable reduced pressure control, compensating for both inlet pressure variations and downstream flow changes, ensuring consistent actuator performance.
- Robust Spool & Sleeve Design: Hardened and ground control spool and sleeve ensure minimal leakage, long service life, and high resistance to contamination and wear.
- Direct-Operated Reliability: No pilot oil required, simplifying circuit design and ensuring fast response, making it suitable for a wide range of industrial applications.
- Adjustable Pressure Setting: The YM adjustment allows precise on-site tuning of the reduced pressure, with a lock nut to secure the setting against vibration.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original REXROTH OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
