The 4WE6D6X/OFEG96N9K4 CSA directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes hydraulic oil to cylinders and motors in automated machinery. It follows the ISO 4401-03-02-0-05 porting pattern for manifold compatibility and tolerates 350 bar at pressure ports P, A, and B. The tank port withstands 210 bar, allowing back-pressure operation, while the valve passes up to 80 l/min in direct-current service. Continuous energization is supported by a 100 % duty cycle, and each coil draws 30 W. Power is supplied through a K4 connector with 2+PE, Design A, and reliable performance is maintained within a ±10 % voltage range.
The electromagnetic drive permits a switching frequency of 4.2 cycles per second, and the coil surface can reach 120 °C under that load, a level accommodated by insulation class F windings. When de-energized, the circuit may see up to 500 V of switch-off overvoltage, so appropriate suppression is required. A concealed manual override (code N9) allows spool actuation during setup and may be used only when tank pressure is below 50 bar. Hydraulic fluid cleanliness must meet ISO 4406 class 20/18/15 to protect the precision spool lands. With both solenoids fitted, the valve weighs 1.95 kg, making it easy to mount on compact manifolds.
