4WE6J6X/EW24N9DA/H18/62

The 4WE6J6X/EW24N9DA/H18/62 directional spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series. Intended for hydraulic automation, it shifts oil paths to start, stop, or change actuator motion in systems where compact form is valuable. The valve is built in size 6, making it suitable for manifolds with limited port spacing. Its solenoid operates on 24 V DC, and a ±10 % voltage tolerance keeps the coil responsive when supply lines fluctuate. Electrical load is limited to a nominal 30 W so panel designers can size power supplies accurately. A duty cycle of 100 % permits the coil to remain energized continuously without damage, while a maximum coil surface temperature of 120 °C and insulation class F work together to protect the winding in hot environments. Protection class IP65 blocks dust and low-pressure water jets, supporting outdoor service. A concealed manual override (N9) lets maintenance staff shift the spool mechanically, and the assembled unit with two solenoids weighs 1.95 kg.

Installation accuracy is promoted by a locating hole that includes a locking pin suffix /62, preventing lateral movement once the valve is tightened to the subplate. The hydraulic interface follows NFPA D03 standards, and the ISO 4401-03-02-0-05 porting pattern aligns each gallery so the valve can replace or be replaced by other size-matched models without plumbing changes. In operation, ports P, A, and B withstand pressures up to 350 bar, enabling use with modern high-pressure pumps; the tank port tolerates 210 bar, which accommodates back-pressure in long return lines. The design passes a maximum flow of 80 l/min, providing adequate capacity for medium-sized cylinders and motors. Because the locating hardware fixes the body firmly, vibration does not affect spool alignment, and the interface standard simplifies future service. Together, the pressure ratings, flow capacity, and standardized footprint allow the valve to control motion reliably across mobile or stationary hydraulic machines that demand compact, interchangeable components.
