Product Overview
The Rexroth HSZ 10 A490-5X/AB-B05G24-AK4M00 (Material Number: R901507576) is a high-precision hydraulic sandwich plate valve block engineered for modular system integration. As part of the Rexroth HSZ 10 series, this component functions as a compact, intermediate flow control element that mounts directly between a directional control valve and its subplate, enabling precise adjustment of actuator speed without the need for additional piping. The valve block features a robust cast iron housing and incorporates a pressure-compensated flow control cartridge, ensuring stable flow rates independent of load fluctuations. With its 24 V DC solenoid actuation and integrated check valve, this sandwich plate valve provides reliable, leak-free performance in demanding industrial hydraulic circuits, making it an essential building block for advanced manifold assemblies.

Engineering Features & Advantages
- Precision Flow Metering: The pressure-compensated cartridge maintains a constant set flow rate regardless of varying load pressures, ensuring repeatable actuator speeds and superior process control.
- Modular Sandwich Design: Compact intermediate plate eliminates external piping, reduces leak points, and simplifies manifold assembly, saving installation time and space.
- Integrated Check Valve: Allows free reverse flow while blocking flow in the controlled direction, protecting the circuit from pressure spikes and ensuring unidirectional metering.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a hardened spool and robust solenoid rated for high cycle life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in interchangeability.
Typical Industrial Applications
This sandwich plate valve block is ideal for hydraulic systems requiring precise speed control of actuators, such as plastic injection molding machines, metallurgical presses, CNC machine tools, and construction & marine hydraulics. It is commonly used in manifold assemblies where
