Bosch Rexroth 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M Proportional Directional Valve R900750127

The Bosch Rexroth 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M proportional directional valve, material number R900750127, is a high‑performance pilot‑operated proportional direction and flow control valve used in industrial and mobile hydraulic systems. It belongs to the Rexroth 4WRZE valve family with integrated electronics (OBE) for precise control of flow direction and size across hydraulic actuators and circuits.

According to Bosch Rexroth official proportional valve technology data, 4WRZE series valves are pilot‑operated, two‑stage, proportional directional valves. They feature integrated control electronics (OBE) and operate via proportional solenoids with central threaded coils. The valves are designed for subplate mounting with porting patterns to ISO 4401 standards. Their proportional control enables smooth adjustment of flow direction and magnitude, improving hydraulic system responsiveness and control performance. :contentReference[oaicite:1]{index=1}

The complete model code 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M contains configuration information that should remain in product titles and quotations. The 4WRZE16 identifies the proportional valve family and size NG16 (ISO 4401‑07 mounting pattern). W8‑150 identifies the particular spool shape and pressure/flow characteristics; 7X is the component series indicating the seventh generation electronics and spool design. 6EG24N9EK31 defines the electrical interface, command input and connector type, while A1D3M defines the command value input type (voltage or current) and installation option.

Bosch Rexroth 4WRZE valves are designed for medium‑ to high‑pressure hydraulic circuits with maximum operating pressure up to 350 bar and nominal flow ranges corresponding to the selected valve size. Their pilot‑operated design with integrated electronics ensures precise proportional control, low hysteresis and repeatable response under varying load conditions. :contentReference[oaicite:2]{index=2}

Typical applications of the R900750127 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M include hydraulic power units, CNC machine tools, presses, test benches, forming machines, industrial automation systems and mobile hydraulics where accurate flow and directional control are critical. Because proportional valves influence motion, force and speed behavior, correct model specification and matching electrical command input are essential for reliable operation.

For procurement teams and maintenance engineers, the key reference for this product is the complete factory model 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M together with material number R900750127. Short descriptions such as “proportional valve” or “Rexroth flow control valve” are not sufficient for accurate replacement, as similar valves vary in spool type, component series, command input and connector options.

Before ordering the Bosch Rexroth 4WRZE16W8‑150‑7X/6EG24N9EK31/A1D3M proportional directional valve, confirm the valve nameplate, hydraulic schematic, electrical command signal type (current or voltage), connector and mounting interface on the existing system. Photos and nameplate details can help ensure correct part selection and installation.
