Product Overview
The Rexroth ZDB6VP2-4X/200V (Material Number R900409844) is a direct-operated pressure relief valve from the proven ZDB6 series, designed in accordance with Rexroth’s modular sandwich plate (stack) valve system. It functions as a pilot-operated pressure limiting device within hydraulic circuits, safeguarding system components against overpressure by diverting excess flow to the tank once the preset cracking pressure is reached. The “VP2” designation indicates a specific adjustment and spool configuration, while the “200V” suffix denotes a nominal pressure setting of 200 bar. This valve is engineered for precise pressure control, low hysteresis, and fast response, making it a critical safety and control element in demanding industrial hydraulic power units and manifold assemblies.

Engineering Features & Advantages
- Precision Pressure Limiting: Direct-operated spool design delivers accurate and repeatable pressure control with minimal hysteresis, ensuring stable system pressure even under fluctuating flow conditions.
- Sandwich Plate Construction: Compact NG6 stackable design allows direct mounting between directional control valves and manifold blocks, reducing piping, leakage points, and installation space.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and seat components providing long service life and resistance to contamination-induced wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in interchangeability for the ZDB6 series and material number R900409844.
- Fast Response Dynamics: Quick opening and closing characteristics protect downstream components from pressure spikes and transient overloads.
Typical Industrial Applications
This pressure relief valve is widely deployed in heavy industrial hydraulic systems, including plastic injection molding machines, metallurgical presses, CNC machine tool power packs, and construction & marine hydraulic manifolds. It is particularly suited for system pressure protection, counterbalance circuits, and as a safety override in complex sandwich plate assemblies where precise, reliable pressure control is essential.
