The 4WRTE25E350L-4X/6EG24EK31/A5M valve functions as a proportional directional unit for closed-loop hydraulic motion control in the 4WRTE Directional Control Valves series by Bosch Rexroth. It is built around nominal size 25, which determines the spool dimensions and overall flow envelope. A port pattern conforming to ISO 4401-08-08-0-05 lets the body bolt directly to standardized subplates, reducing installation work. Each working and pressure port (p, a, b, t) is 32 mm in diameter so that full-bore passages remain unrestricted. With a rated flow of 350 l/min the valve can command sizable cylinders or motors without excessive pressure drop. The main stage withstands 350 bar on ports p, a, and b, enabling high-pressure operation in presses or plastic machines. Pilot oil is supplied internally, eliminating separate feed lines, while an external pilot return keeps the control chamber free of backpressure for consistent spool positioning.
For electrical control, the integrated electronics accept a ±10 V command signal, and the 100 kΩ input resistance keeps the demand on the drive amplifier low. A nominal supply of 24 V DC powers the circuitry; tolerance from 18 V to 35 V DC allows continued service during line fluctuations. Current draw peaks at 1.6 A, a value used when selecting power supplies and fuses. The return line at port T may carry up to 250 bar, permitting installation in systems with elevated tank pressures, whereas the drain at port Y is limited to 10 bar to protect the pilot stage seals. Environmental protection is rated IP65, so the housing resists dust ingress and low-pressure water jets in typical factory settings. These characteristics support precise, repeatable actuation of hydraulic actuators in automated production lines.
