4WE6J5X/BG24NVP1Z2

The 4WE6J5X/BG24NVP1Z2 valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic oil to actuators in automated machinery by shifting an electrically driven spool. The spool carries the symbol J, which determines how pressure, tank, and work ports are interconnected during each switching state to obtain the required actuator motion. A fixed spool position B establishes the default flow pattern when the coil is not energized. Installation uses the ISO 4401-03-02-0-05 (D03) mounting interface so the body bolts directly to standard subplates without adapters. The energizing circuit operates on a nominal voltage of 24 V DC, and the coil draws a rated current of 1.25 A to produce the magnetic force needed for reliable shifting. Electrical consumption is held to a nominal power of 30 W, supporting low-heat continuous service. A duty cycle of 100 % ED allows the coil to remain powered indefinitely, while insulation class F provides adequate thermal endurance for the winding.

The coil surface may reach up to 120 °C, so enclosure ventilation must keep ambient temperatures below this limit. The main pressure ports a, b, and p withstand operating pressures up to 350 bar, enabling the valve to control high-pressure circuits, whereas the tank port is limited to 210 bar to protect return-line components. A maximum flow rate of 80 l/min defines the throughput the internal passages can accommodate without excessive pressure loss. Hydraulic oil cleanliness must meet ISO 4406 class 20/18/15 to prevent spool sticking and premature wear. FKM seals maintain tight sealing under the fluid types and temperatures common in high-performance systems. There is no manual override, so actuation depends solely on the electrical signal for consistent remote control. The single-solenoid version weighs 1.45 kg, which simplifies handling during assembly and maintenance.
