The 4WEH16J7X/6EG24N9ETS2K4/B10V valve is manufactured by Bosch Rexroth within the WEH Directional Spool Valves series and directs hydraulic flow for automated machinery. It routes fluid through four ports to support bidirectional actuator control. The unit uses a nominal size 16 interface, which defines mounting dimensions and flow capacity. A porting pattern of ISO 4401-07-07-0-05 aligns the body with standard subplates for quick installation. Flow paths conform to spool symbol J, providing a defined crossover that limits pressure shocks. Internal pilot oil supply and return remove the need for external pilot lines and simplify manifold design. A concealed manual override allows technicians to shift the spool during setup without exposing the mechanism. Electrical actuation is provided through a DIN EN 175301-803 connector powered by 24 V DC, matching common control voltages in industrial plants.
The valve handles operating pressures up to 280 bar, while its pilot stage withstands 250 bar to ensure dependable shifting under load. FKM seals and an ambient limit of 50 °C permit use with mineral oil fluids in warm machine compartments. ISO 4406 cleanliness class 20/18/15 is required to keep the precision edges free of abrasive particles, so appropriate filtration must be installed. A Ø 1.0 mm throttle insert can be added to meter pilot flow and soften spool movement. Discharge-type switching time adjustment further refines response by controlling pilot exhaust. These pressure and damping features support stable motion control across varying duty cycles, making the valve suitable for presses, test rigs, and general automation equipment.
