It houses a directional seat valve module (W/S) within the block, enabling pilot control of hydraulic actuators in tight-space hydraulic assemblies. Verified specifications include a maximum operating pressure up to 350 bar and a maximum flow up to 30 L/min, making it suitable for precise, responsive control in compact hydraulic circuits. The WZ4-M/V suffix indicates the specific coil/actuation variant for this IH15EB-1X module, designed for integration with Rexroth control elements in modular valve stacks. This valve block is typically used in industrial automation equipment and machine-tool applications where a small footprint and reliable pilot control are essential for coordinating multiple hydraulic functions in a single compact unit.
