The 4WE6G73-6X/EG24N9K4/A12/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation circuits. A mounting pattern of ISO 4401-03-02-0-05 lets the valve fit standard sub-plates, while the NFPA T3.5.1 D03 interface keeps it interchangeable with North American manifolds. A clamping length of 42 mm secures the body firmly to the base block. The two-solenoid version weighs 1.95 kg, which limits manifold mass. Electrical power is supplied at 24 V DC, and a rated current of 1.25 A drives the coils to full stroke without overheating. A 3-pin (2+PE) DIN EN 175301-803 connector enables quick wiring and earth continuity. A concealed manual override is included so technicians can shift the spool during setup without exposing the mechanism to contaminants.
The valve tolerates a maximum operating pressure of 350 bar on ports P, A, and B, making it suitable for high-pressure loops, while tank port D is limited to 210 bar to protect return lines. A maximum flow of 80 l/min supports mid-range actuator speeds. Smooth switching behavior identified as A12 minimizes pressure shocks during spool movement. The K4 coil housing carries an IP65 protection class to block dust and water jets in wet plant zones. System oil must meet ISO 4406 cleanliness code 20/18/15 to prevent spool sticking. The manual override withstands 50 bar back-pressure to the tank, ensuring emergency shifts remain possible. A locating hole with an ISO 8752-3x8-St pin guides the body into the sub-plate for accurate port alignment, rounding out the features needed for reliable flow direction control in compact hydraulic manifolds.
