The 4WRA10W60-2X/G24N9K4/V-589 proportional directional valve belongs to the 4WRA Proportional Directional Valves series produced by Bosch Rexroth for closed-loop hydraulic automation. It meters flow and directs pressure-balanced ports by converting coil current to spool position. The unit operates on a 24 V DC supply so it can be connected directly to common machine control power, and the upper voltage limit of 35 V protects the coil against transient overvoltage. A maximum amplifier current of 1.8 A establishes the controlled range for steady actuation, while an impulse current up to 3 A permits fast spool acceleration during step changes. Nominal size 10 defines the port pattern for subplate mounting, and a nominal flow of 60 l/min at a 10 bar differential delivers the baseline capacity for servo loops. Maximum operating pressure of 315 bar on ports a, b, and p allows use in high-pressure circuits, and the T port withstands 210 bar to secure return-line integrity. The valve weighs 6.6 kg, enabling direct manifold installation without additional supports.
The permitted fluid is mineral oil to DIN classes HL or HLP, and FKM seals are installed so the valve resists these media at elevated temperatures. System filtration must achieve ISO 4406 20/18/15 cleanliness, ensuring the precision spool remains free of abrasive particles. Electrical connection follows the DIN EN 175301-803 standard, allowing use of molded cable plugs for quick service exchange. Under steady command the hysteresis does not exceed 5 %, and response sensitivity remains better than 0.5 %, which supports finely graded position control in servo presses or plastic machines. During polarity shifts the reversal error stays below 1 %, limiting offset drift between forward and reverse flow. The design accepts a continuous flow up to 75 l/min so oversizing of the pump is unnecessary when momentary peaks occur. In combination these characteristics provide repeatable directional change without undue leakage or spool lag.
