The 4WE6D5X/BG12-12NXHZ2/V directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation. It is designed to route pressurized fluid between actuator ports in compact power units, and its nominal size 6 defines the porting dimensions used in these circuits. The subplate mounting interface follows ISO 4401-03-02-0-05, while the NFPA pattern T3.5.1 R2-2002 D03 provides interchangeability with North American manifolds. A maximum flow of 80 l/min can pass through the valve, and a maximum operating pressure of 350 bar allows use in high-pressure systems. The coil may remain energized continuously because the duty cycle is rated at 100 % ED, and a voltage tolerance of ±10 % keeps performance stable with minor supply variation. An FKM seal is fitted to resist common hydraulic oils, and the assembled unit carries an IP65 protection class that shields the electrical section from dust and water jets.
The valve’s solenoid operates on a nominal voltage of 12 V DC and draws a rated current of 2.5 A, resulting in a nominal power demand of 30 W during steady energization. Insulation class F winding material allows the coil to withstand internal temperatures associated with this load, and the permitted coil surface temperature reaches 120 °C before derating is required. When the coil is de-energized, the circuit must accommodate a switch-off overvoltage up to 500 V, so appropriate transient suppression is necessary. The design supports a maximum switching frequency of 4.2 cycles per second, enabling rapid directional changes in proportional control schemes without overheating or magnetic saturation. These electrical limits complement the hydraulic data stated earlier and confirm that the 4WE6D5X/BG12-12NXHZ2/V valve can respond quickly while maintaining thermal stability in continuous industrial service.
