The Bosch Rexroth 4WRREH is a high-response proportional directional valve with integrated electronics, built for precise electro-hydraulic control where a standard proportional valve would be too slow to sit inside the control loop. Twin Hydraulics Engineering supplies 4WRREH valves across Malaysia.
Valves in this class are chosen for servo-hydraulic duty: closed-loop force, position and velocity control on test and simulation rigs, press and forming control, and any axis where a motion controller is correcting the command many times a second. Integrated electronics remove the separate amplifier card from the bill of materials and keep the spool position loop close to the valve.
Only a small number of 4WRREH type codes are listed here. If yours is not among them, send us the code from the nameplate — this family is largely built to order and we can quote from the code and material number.
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.
