Rexroth Proportional Valve 4WREE6W1-32-2X/G24K31/F1V 315 Bar High Pressure Easy To Calibrate High Temperatures Up To 80 °C

Description:

The Rexroth 4WREE6W1-32-2X/G24K31/F1V is a direct-acting three-position four-way proportional directional valve manufactured by Bosch Rexroth. It features a 6 mm bore, belongs to the 2X series, has a maximum operating pressure of 315 bar, and a rated flow rate of 32 L/min (Δp = 10 bar). The valve features a plate-mounted design, with port arrangements compliant with ISO 4401-03 / DIN 24340-A / CETOP RP121H standards, enabling direct replacement of conventional electromagnetic directional control valves of the same specifications. The spool is driven by a proportional solenoid and integrates a displacement sensor to achieve closed-loop feedback of the spool position; An internal amplifier (F1 interface, 4–20 mA command input) enables connection to an upper-level PLC or motion controller with a single cable, eliminating the need for an external amplifier card. The solenoid coil features a central thread, enabling 360° rotation and quick disassembly/replacement for easy maintenance. The valve spool and body are treated with a hard coating and paired with fluor rubber seals, offering wear and corrosion resistance suitable for mineral oil, water-glycol, and phosphate ester hydraulic fluids. Flow-current characteristic curves and temperature drift compensation are matched and compensated during factory testing to ensure batch consistency. The compact and lightweight all-aluminum alloy housing reduces installation space by over 30% compared to traditional servo valves, while achieving dynamic response times of less than 50 ms, sufficient to meet most industrial closed-loop control requirements.
 

Application Areas:

Injection Molding Machines: Speed and force control of clamping, injection, and ejection actuators
