Product Overview
The Rexroth ZDR6 DP2-4X/150YM (Material No. R900483787) is a direct-operated, three-way pressure reducing valve from the proven ZDR6 series, designed for precise secondary pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve maintains a constant reduced outlet pressure regardless of fluctuations in the primary (inlet) pressure or changes in flow demand. The “DP2” designation indicates a direct-operated pressure reducing valve with a specific adjustment and spring configuration, while the “150YM” suffix denotes a 150 bar pressure rating with a specific adjustment type. The valve operates on a spool-in-sleeve principle, where the control spool modulates the flow path to maintain the set reduced pressure at the secondary port. This model is widely used as a reliable, compact solution for limiting pressure in sub-circuits, clamping systems, and actuator control lines within complex hydraulic circuits.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated spool-in-sleeve design ensures accurate and stable reduced pressure control, minimizing hysteresis and pressure overshoot even under varying flow conditions.
- Three-Way Functionality: In addition to reducing inlet pressure, the valve provides a relief function from the secondary side to the tank port, protecting downstream components from pressure spikes and enabling rapid pressure decay when the setpoint is reduced.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction, hardened spool and sleeve, and proven Rexroth quality standards for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
- Compact Subplate Design: NG6 / CETOP 3 mounting pattern allows space-saving integration into modular hydraulic power units and control blocks.
Typical Industrial Applications
This pressure reducing valve is commonly employed in plastic injection molding machines for clamping and injection pressure control, metallurgical presses for precise
