The 4WE6E6X/EG24N9DK24L belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route hydraulic flow in automated machinery. It operates on a nominal 24 V DC supply, making it compatible with common control voltages, and draws a rated current of 1.25 A so power modules can be selected accurately. The coil absorbs 30 W in direct-current service, establishing the heat that must be removed during continuous duty; this is possible because the duty cycle is specified at 100% ED, permitting uninterrupted energization. A maximum coil surface temperature of 120 °C defines the thermal limit to protect winding insulation. Connection is through an M12×1 four-pole plug, which provides a compact, keyed interface for quick field wiring. The valve is assigned Protection Class III, indicating it must be powered by a safety extra-low-voltage source, and an IP65 ingress rating shields the housing against dust and low-pressure water jets, enabling reliable operation in industrial wash-down zones.
The porting pattern follows ISO 4401-03-02-0-05, allowing direct mounting on standardized CETOP 3 subplates without adapter blocks. A maximum flow of 80 l/min supports medium-capacity cylinders and motors, while a 350 bar limit on pressure at ports P, A, and B lets the spool handle high-pressure supply and actuator lines. The T port is rated for 210 bar, defining the permissible backpressure in return circuits. Switching can occur up to 4.2 cycles per second, which sets the speed for repetitive positioning tasks. Switch-off overvoltage is limited to 500 V, so external suppression may be required to protect control electronics. Hydraulic fluid must meet ISO 4406 class 20/18/15 cleanliness to minimize wear and prevent spool sticking, completing the operational boundaries for dependable directional control.
