The Bosch Rexroth 4WRGE is a high-response pilot operated proportional directional valve in sizes NG10, NG16 and NG25, with on-board electronics and spool position feedback. High-response means a faster step response and lower phase lag than a standard proportional valve — the difference between a valve that follows a command and one that can sit inside a fast closed control loop. Twin Hydraulics Engineering supplies 4WRGE valves across Malaysia.
That responsiveness matters wherever the controller is correcting continuously rather than simply ramping: servo-hydraulic test benches, fatigue and materials testing, press force and position control, simulator and shaker tables, and rolling-mill gauge control. The integrated electronics keep the loop tight and remove the amplifier card from the specification.
If your application only needs smooth ramping rather than high bandwidth, a standard proportional valve is the cheaper and more robust choice — see 4WRZ / 4WRH or 4WRDE for the same sizes.
What we need to quote: the full type code and material number from the valve nameplate, coil or OBE supply voltage, command signal (±10 V, 4–20 mA or IO-Link), connector type, and quantity. If you are replacing a valve, a nameplate photo plus the amplifier card model is ideal.
