The 4WE6J6X/EG24NK40/Z/62SO43A-1872-A AN directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and routes pressure and return lines in automated hydraulic systems. It fastens to a manifold through the NFPA T3.5.1 D03 mounting interface, while the ANSI B93.9 and ISO 4401-03-02-0-05 porting patterns align the pressure, tank, and work ports with standard subplates. A clamping length of 22 mm secures the solenoid assembly to the housing, and an ISO 8752-3x8-St locating pin positions the body precisely on the mounting surface. Electrical power is supplied through a DT04-2PA Deutsch connector; the K40 version of this interface carries an IP69K protection class to resist high-pressure wash-down. The coil operates at a nominal 24 V DC and accepts a ±10 % voltage swing, drawing 30 W during steady excitation to open or close the spool.
The solenoid is rated for a 100 % ED duty cycle, allowing continuous energization without duty-related downtime, and the maximum coil surface temperature of 120 °C defines the thermal ceiling for safe operation. Hydraulic performance reaches 350 bar on the pressure, A, and B ports, while the tank port is limited to 210 bar to protect return circuitry. A maximum direct-current flow of 80 L/min lets the valve manage medium-sized actuator demands, and a switching frequency of 4.2 cycles per second supports rapid but stable directional changes. Together, the pressure ratings, flow capacity, and frequency limit keep internal forces within design margins during continuous service, enabling reliable flow direction control in hydraulic automation tasks.
