The 4WRTE25V220L-4X/6EG24K31/A1V valve belongs to the 4WRTE Directional Control Valves series produced by Bosch Rexroth for hydraulic automation systems. It employs a linear flow characteristic to produce proportional metering of oil and achieve smooth actuator positioning. Nominal size 25 defines the internal cavity dimensions and matches manifolds designed for medium-flow circuits. A rated flow of 220 l/min at a 5 bar pressure drop supports high cylinder speeds, while a spool symbol V specifies the port interconnection pattern used to direct flow between P, A, B, and T. The porting pattern conforms to ISO 4401-08-08-0-05 so the unit can bolt to standard subplates. Maximum operating pressure of 350 bar on ports P, A, and B permits use in presses and injection machines. FKM seals resist synthetic and mineral oils at elevated temperatures, and cleanliness class ISO 4406 18/16/13 limits particle contamination to protect the precision‐ground spool.
A 24 V DC supply powers the integrated proportional solenoids, and a ±10 V electrical interface receives the position command from the motion controller. Normal current consumption is 1.6 A, with a 2.7 A impulse current used during rapid spool shifts. Continuous service is possible because the duty cycle is 100 percent, and the electrical load is capped at 72 VA to simplify power budgeting. The enclosure carries an IP65 protection class so the electronics are shielded from dust and low-pressure jets of water. Total weight is 16.8 kg, which affects mounting bracket selection in mobile or stationary installations. These electrical and mechanical features combine to provide repeatable flow control in demanding industrial hydraulic circuits.
