4WE6J5X/BG12-12NXHZ2/V

The 4WE6J5X/BG12-12NXHZ2/V valve is produced by Bosch Rexroth and belongs to the WE Directional Spool Valves series. The component directs hydraulic flow to actuators in automated machinery. Its nominal size is 6, which aligns with compact manifolds where space is limited. A mounting interface specified as ISO 4401-03-02-0-05 ensures interchangeability with standard subplates. The valve follows NFPA size D03 so it fits into common North American circuit layouts. Maximum pressure at the P, A, and B ports reaches 350 bar, allowing use in high-pressure systems, while maximum flow in direct current operation is 80 l/min to satisfy medium-duty cylinder speeds. The unit omits a manual override, preventing unauthorized shifting during operation. An FKM seal set resists synthetic fluids and elevated oil temperatures. Continuous duty is supported by a 100 percent ED rating, meaning the solenoid may remain energized without a rest period.

The wet-armature coil operates on 12 V DC, and a rated coil current of 2.5 A produces the magnetic force needed to move the spool. Nominal electrical input is 30 W, which simplifies power supply sizing in mobile or stationary equipment. Voltage tolerance of ±10 percent keeps the valve responsive despite minor supply fluctuations. A switching frequency of 4.2 operations per second accommodates rapid cycling in servo-controlled loops. Maximum coil surface temperature is limited to 120 °C; this ceiling protects insulation when the valve is mounted near hot hydraulic manifolds. The tank port may see pressures up to 210 bar without compromising return line integrity. All remaining performance values apply to direct current service, maintaining consistency with the target control architecture. Together, these electrical limits and thermal ratings complement the hydraulic data given earlier and define the operating envelope for reliable spool actuation in automated hydraulic circuits.
