4WE6J6X/EW110N9DA/H08V/62

The 4WE6J6X/EW110N9DA/H08V/62 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs pressurized fluid to selected actuator ports in hydraulic automation. It uses nominal size 6 passages to fit compact manifolds while maintaining adequate flow capacity. Mounting follows the ISO 4401-03-02-0-05 interface, so the manifold pattern is standardized across compatible subplates. A maximum flow rate of 60 l/min allows the unit to service medium-duty circuits without exceeding recommended velocity limits. Ports p, a, and b can be pressurized to 350 bar, which supports high-pressure work functions such as clamping or pressing. The tank port tolerates up to 160 bar when the coil is powered by an AC supply, protecting return lines from pressure peaks. A throttle insert with a 0.8 mm orifice in port A provides optional damping to reduce spool shift shocks when flow is reversed. For manual actuation during commissioning, a concealed N9 override is fitted, and FKM seals resist aggressive hydraulic fluids at elevated temperatures.

The solenoid is designed for a 110 V AC supply at 50 or 60 Hz, enabling direct connection to common control transformers. Continuous energization is permissible because the duty cycle is rated at 100% ED (S1), so coil heating does not mandate rest periods. On energization the valve draws 220 VA as switch-on power to overcome static friction and move the spool rapidly. Once the spool is seated, holding power drops to 50 VA, reducing steady-state energy consumption and heat generation. The coil accepts a voltage variation of ±10%, which maintains reliable shifting despite supply fluctuations. A maximum switching frequency of 2 Hz limits the actuation rate to ensure the magnetic circuit and seals are not overstressed. Under prolonged service the coil surface may reach 120 °C, so surrounding components must tolerate that temperature.
