The 4WE6H6X/EG24N9DAL directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs pressurized hydraulic fluid to cylinders or motors in automated machinery. The valve is built to nominal size 6, and its subplate interface follows ISO 4401-03-02-0-05 (D03) so it fits standard manifolds. Ports a, b, and p accept operating pressures up to 350 bar, while the t port withstands 210 bar, allowing reliable return-line operation in high-pressure circuits. A maximum flow capacity of 80 l/min permits moderate throughput without excessive pressure drop, and a switching frequency of 4.2 cycles per second supports rapid actuation duties. The concealed N9 manual override enables local shifting when electrical power is unavailable, and the required fluid cleanliness is ISO 4406 class 20/18/15 to prevent spool wear and sticking.
Continuous solenoid energization is possible because the valve is rated for a 100% ED duty cycle. The coil operates on 24 V DC and draws 1.25 A, so common machine control supplies can drive it without additional conversion. A voltage tolerance of ±10% keeps performance stable during supply fluctuations, and the winding consumes 30 W of nominal power to establish the necessary magnetic force. Insulation class F materials permit winding temperatures that accompany a coil surface limit of 120 °C, prolonging service life under sustained load. Electrical entry is provided through an NPT 1/2-14 cable gland marked DAL, simplifying conduit installation in industrial panels.
