4WE6D46-6X/OFEG24N9K72LSO407

The 4WE6D46-6X/OFEG24N9K72LSO407 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It redirects hydraulic flow to start, stop, or reverse motion in automated machinery. The solenoid is energized with 24 V DC, and a voltage tolerance of ±10 % keeps the coil functional when the supply fluctuates. An M12x1, four-pole connector provides straightforward electrical hookup, while the coil’s 8 W power draw minimizes heat inside control enclosures. Continuous actuation is permitted because the unit is rated for a 100 % duty cycle. Command signals must not exceed one shift per second, a restriction that protects the mechanical parts and fluid stability. When the coil is de-energized, it withstands switch-off overvoltages up to 500 V, safeguarding the insulation. The housing meets the IP65 protection class, sealing the valve against dust and low-pressure water spray commonly present on production lines.

A concealed manual override allows technicians to move the spool mechanically during commissioning or power loss events. The coil surface temperature can reach 85 °C under sustained load, so adequate ventilation is required in tight manifolds. The valve passes up to 60 L/min of hydraulic fluid, making it suitable for medium-flow circuits. Ports a, b, and p handle pressures to 315 bar, while the tank port t is limited to 210 bar to protect return-line components. Mounting follows the ISO 4401-03-02-0-05 porting pattern, enabling direct installation on standardized subplates without adapters. A single solenoid weighs 1.45 kg, a factor to consider when calculating manifold support and transport loads. These characteristics equip the valve for reliable service in hydraulic automation tasks that require consistent switching, controlled temperature rise, and high working pressure.
