Product Overview
The Rexroth HSZ 06 A217-3X/05-AS10G-DS100WGU (Material Number: R900555867) is a high-precision hydraulic sandwich plate valve block engineered for modular circuit integration within industrial hydraulic systems. Manufactured by Bosch Rexroth under the trusted Rexroth hydraulic valve program, this unit functions as a compact intermediate flow control element that is sandwiched between a directional control valve and a subplate or manifold, enabling targeted flow regulation, pressure compensation, or load-holding functions without additional piping. The HSZ series is a proven modular valve platform used extensively in manifold block assemblies where space efficiency, leak-free sealing, and repeatable metering accuracy are critical. With a size 06 (NG6 / CETOP 3) interface, the valve block delivers reliable performance in continuous-duty industrial circuits, supporting precise actuator control and optimized system response.
