Bosch Rexroth: A Brief History

Bosch Rexroth traces its origins to a water-powered hammer mill and foundry in Lohr am Main in 1795. By the 1950s, it had entered the hydraulic technology market. Over time, the company expanded its product range to include electrical drives, controls, and assembly technologies. In 2001, the merger of Mannesmann Rexroth with Bosch Automationstechnik led to a company focused on integrated Drive & Control technologies. Bosch Rexroth has since continued to develop its portfolio, which includes the 4WRE series of hydraulic valves, contributing to advancements in industrial automation.

4WRE / 4WREE Series Valves

Rexroth 4WRE and 4WREE series valves are direct operated proportional control valves, available in sizes 6 to 10,  designed to fine-tune the direction and magnitude of fluid flow within your machinery. Their standout feature is the integral feedback mechanism that ensures consistent performance.

The versatility of these valves is further enhanced by options for on-board electronics (OBE) in the 4WREE models, simplifying integration and control within your systems. Mounting compatibility isn’t a concern either, thanks to adherence to ISO, NFPA, and ANSI standards. This ensures they can easily replace or fit into existing setups.

Performance metrics include a maximum operating pressure of up to 315 bar and flow capacities that meet various industrial demands—up to 80 l/min for size 6 and up to 180 l/min for size 10. Proportional solenoids enable precise control, while spool overlap options allow custom adjustments for leakage reduction or closed-loop functions.

Key models include:
- 4WRE 6 E16-2X/G24K4/V
- 4WREE 10 E50-2X/G24K31/A1V
- 4WREE 10 E75-2X/G24K31/A1V
- 4WREE 6 E08-2X/G24K31/A1V
- 4WREE 6 V16-2X/G24K31/A1V
- 4WREE 6 EA16-2X/G24K31/A1V

Whether you're implementing new systems or optimizing existing ones, these valves offer dependable solutions for rigorous control tasks.
