Product Overview
The Rexroth 4WREE6W32-3X/V/24F1 (Material Number: R901496438) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. Part of the renowned Rexroth 4WREE series, this valve features a 4-way, 3-position spool configuration with a “W32” spool type, providing a specific flow characteristic suited for demanding metering applications. The “3X” designation indicates the component series, reflecting Rexroth’s third-generation design improvements in spool geometry, solenoid force optimization, and contamination resistance. The integrated 24V DC proportional solenoid (24F1) enables stepless, infinitely variable control of spool position, which is directly proportional to the electrical input signal. This valve is engineered to deliver exceptional dynamic response, low hysteresis, and high repeatability, making it an ideal choice for closed-loop position, velocity, and force control in injection molding machines, metallurgical equipment, and advanced test rigs. As a direct-operated valve, it ensures reliable performance even at low pressure differentials and provides fail-safe operation by returning to the spring-centered neutral position upon power loss.
