The 4WE6D73-6X/OFEG24N9DK35L/A12 CSA AN directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. The unit directs hydraulic flow in automation circuits by shifting a two-position spool that is held by a detent, so no spring return is present. Its size 6 body follows the ANSI B93.9 porting pattern to align with standard subplates. A 24 V DC coil actuates the spool, drawing 1.25 A and consuming 30 W, which suits common machine control supplies. The coil supports a 100 % duty cycle, allowing continuous energization without thermal overload, and the maximum switching frequency of one actuation per second prevents excessive wear in rapid-cycle service.
During operation the valve tolerates up to 350 bar on pressure ports while the tank port is limited to 210 bar, enabling high-pressure circuits with controlled return flow. It passes a maximum of 80 l/min, supplying adequate volume for medium-capacity actuators. The enclosure carries an IP65 protection rating, so dust and water jets do not impair performance. Electrical connection is handled by an M12×1 four-pole DK35L plug, allowing quick coil replacement and secure wiring. Coil surface temperature may reach 120 °C under heavy load, a limit designers must respect for insulation and nearby components. Overall weight is 1.95 kg, making installation straightforward without special lifting equipment.
