4WE6D6X/OFEG24DK72L

The 4WE6D6X/OFEG24DK72L valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation systems that require reliable control of actuator flow paths. It mounts to manifolds using the ISO 4401-03-02-0-05 interface so installers can substitute it into common CETOP 03 ports without reworking the block. The solenoid windings are designed for a nominal supply of 24 V DC, and they draw a rated current of 1.25 A, establishing the electrical sizing for the machine’s power supply and protection devices. Electrical consumption remains at 30 W, keeping heat generation predictable for enclosure designers. A voltage tolerance of ±10 % allows the coil to remain within force limits when the supply fluctuates during start-up or battery operation. The unit carries a 100 % duty cycle (S1), which means it may stay energized continuously without exceeding thermal limits. Windings are built to insulation class F, permitting higher allowable temperatures and extending service life under demanding cycles. The housing meets IP65, so dust ingress and low-pressure water jets will not affect operation in mobile or wash-down environments. With two solenoids installed the assembly weighs 1.95 kg, enabling straightforward handling during maintenance.

For hydraulic performance the valve handles a maximum operating pressure of 350 bar on ports P, A, and B, letting designers use it in high-pressure circuits for cylinders or motors. Flow capacity reaches 80 l/min, providing adequate volume for medium size actuators without excessive pressure loss. Port T can accept up to 210 bar, which allows the return line to operate under back-pressure conditions common in load-holding circuits. Switching dynamics are supported by a maximum frequency of 4.2 cycles per second, helping achieve rapid directional changes in automated sequences. The coil surface temperature is limited to 120 °C so thermal sensors can be set below this threshold to safeguard insulation. During de-energization the system must accommodate up to 500 V of switch-off overvoltage, typically by using fly-back diodes or surge suppressors in the control cabinet. A mean time to dangerous failure of 300 years reflects a low probability of random failure and supports high safety integrity levels. These hydraulic, thermal, and reliability figures define the intended operating envelope for the 4WE6D6X/OFEG24DK72L in industrial machinery.
