The 4WE6D6X/OFEG12N9K40SO43A-1799 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for controlling hydraulic actuators in automated machinery. It is built in size 6 and installs on subplates that follow the ISO 4401-03-02-0-05 porting pattern. The flow path accommodates up to 80 l/min while the a, b, and p ports sustain 350 bar, enabling high-pressure circuit design. Electrical actuation uses a 12 V DC supply; at this level the coil draws 2.5 A and consumes 30 W. The unit continues to operate within specification when the supply varies by ±10%, making it suitable for mobile equipment with fluctuating battery voltage.
A 100% ED duty cycle permits continuous energization, and the coil surface may reach 120 °C without exceeding thermal limits. When the coil is disconnected, transient peaks up to 500 V are tolerated to protect the winding insulation. An IP69K housing shields the assembly from dust and high-pressure wash-down. Power is routed through a DT04-2PA Deutsch connector that simplifies field replacement. A concealed N9 manual override allows spool shifting during power loss, and an OF detent holds the spool in its last position after actuation. The tank port handles up to 210 bar of back-pressure, supporting systems where return lines run at elevated pressure.
