The 4WE6J6X/EG12N9K4/62SO43A-1723 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and routes pressurized fluid to cylinders or motors in hydraulic automation. It tolerates operating pressures up to 350 bar on pressure and work ports and supports a continuous flow of 80 l/min to keep medium-capacity circuits responsive. Electrical power is supplied through a DIN EN 175301-803 K4 connector to a 12 V DC coil that draws 2.5 A. The coil consumes 30 W and remains stable within a voltage window of ±10 %, giving predictable switching performance. An IP65 enclosure rating protects internal parts from dust and low-pressure water.
A concealed manual override allows the spool to be shifted during commissioning or power loss, and an ISO 8752-3×8-St locating pin positions the valve accurately on its mounting surface. NBR sealing elements keep external leakage low and are compatible with common hydraulic fluids. The coil surface temperature may reach 120 °C at full duty, while direct-current actuation can be repeated up to 4.2 times per second without overheating. Tank port pressure is allowed up to 210 bar, matching high-pressure return lines in modern systems. The design achieves a mean time to dangerous failure of 300 years, which supports long service intervals in safety-rated machinery.
