The 4WE6J6X/EG12N9K40SO43A-1799 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic actuation in automation systems. Its nominal size is 6, which establishes the flow path dimensions for D03 manifold mounting. The valve installs on an NFPA T3.5.1 D03 interface to align with common subplate layouts, and its porting pattern follows ISO 4401-03-02-0-05 so that ports match standard hydraulic plates. Pressure ports p, a, and b withstand up to 350 bar, enabling use in high-pressure circuits, while the tank port is limited to 210 bar to protect return lines. A maximum flow of 80 l/min can pass through the spool without exceeding performance limits. The solenoid may operate continuously because the duty cycle is 100 percent ED, and an IP69K protection class seals the coil and connector against dust and high-pressure water.
The solenoid runs on a nominal voltage of 12 V DC and draws 2.5 A, resulting in a 30 W power requirement during normal operation. Voltage tolerance of ±10 percent keeps the coil functional under supply fluctuations, and connection is made through a DT04-2PA Deutsch two-pin plug for secure wiring. The coil insulation is class F, confirming thermal endurance for elevated winding temperatures, and the coil surface may reach 120 °C without surpassing its limit. Hydraulic fluid cleanliness must be 20/18/15 per ISO 4406 to prevent wear and blockage. These electrical, thermal, and fluid requirements ensure 100 percent duty performance in demanding hydraulic control applications.
