Product Overview
The Rexroth DA6VP2B50/200FSM (Material Number: R901224238) is a pilot-operated pressure unloading valve engineered for precise control of system pressure in industrial hydraulic circuits. As a member of the DA series, this valve automatically unloads pump flow to tank when a predetermined pressure setpoint is reached, reducing energy consumption and minimizing heat generation during idle or low-demand phases of the machine cycle. The valve features a robust spool-and-sleeve design with an adjustable pressure setting, enabling fine tuning of the unloading and reloading thresholds to match specific system requirements. With a nominal pressure rating of 200 bar and a size 50 interface, the DA6VP2B50/200FSM is designed for direct integration into standard hydraulic power units and manifold blocks, providing reliable pressure control in continuous industrial duty.

Engineering Features & Advantages
- Precision Pressure Control: Pilot-operated spool design delivers accurate and repeatable unloading and reloading pressure thresholds, ensuring stable system pressure regulation across varying flow demands.
- Energy Efficient Operation: Automatically diverts pump output to tank at the set pressure, reducing power consumption and minimizing heat buildup during holding or idle phases.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve components that resist wear and maintain performance over extended service intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
- Adjustable Setpoint: The FSM adjustment variant enables precise field tuning of the unloading pressure to match specific application requirements.
Typical Industrial Applications
This pressure unloading valve is widely used in hydraulic power units for plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial hydraulic systems where controlled pressure relief and energy-efficient pump unloading are required. It is also suitable for construction machinery, marine hydraulic systems, and test stands demanding reliable pressure control up to 200 bar.
