The 4WE6X5A6X/EG24N9K4 CSA valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic oil to actuators and returns fluid to tank in automated machinery. The nominal size 6 sets the interface dimensions for mounting in compact manifolds. A porting pattern of ISO 4401-03-02-0-05 allows the valve body to bolt to metric subplates, while the NFPA interface T3.5.1 R2-2002 D03 maintains interchangeability with D03 base plates. The flow path can carry up to 80 l/min, supporting medium flow circuits. Service ports p, a, and b withstand 350 bar, and the tank port limit is 210 bar, enabling use in high-pressure systems. Electrical actuation consumes 30 W from a 24 V DC supply at a rated current of 1.25 A. The coil tolerates a ±10 % deviation from nominal voltage, preventing malfunctions when the supply fluctuates.
Continuous-duty operation is possible because the solenoid is rated for a 100 % ED duty cycle. Insulation class F permits allowable winding temperatures that rise without damage, and the coil surface may reach 120 °C before exceeding limits. An IP65 protection class keeps dust and water jets from entering the envelope so the valve survives on exposed machine frames. Electrical hookup uses a K4 connector built to DIN EN 175301-803, giving quick plug-in service connections. A concealed N9 manual override lets maintenance staff shift the spool without energizing the solenoid, yet remains flush with the housing to avoid accidental actuation. Its construction supports frequent switching demanded by sequence controls in assembly or handling equipment, and these features combine to support reliable, long-term hydraulic flow control within automation cells.
