The 4WE 6 JB6X/EG24N9DA/B15/62 valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series for electrically actuated flow direction control in hydraulic automation systems. Its solenoid operates on a nominal voltage of 24 V DC and consumes 30 W, while a voltage tolerance of ±10 % safeguards function when supply fluctuates. Continuous energization is permissible because the duty cycle is 100 % ED; insulation class F and a maximum coil surface temperature of 120 °C prevent thermal damage. The spool can switch up to 4.2 times per second to meet rapid cycling demands, and the mean time to dangerous failure is 300 years to support safety-related installations.
Hydraulic limits allow the valve to withstand 350 bar at the pressure and working ports and to pass a maximum flow of 80 l/min, with the tank port tolerating 210 bar during return flow. It attaches to manifolds through the NFPA T3.5.1 D03 mounting interface, and the porting pattern follows ISO 4401-03-02-0-05 for interchangeability across subplates. A concealed manual override designated N9 lets technicians shift the spool when the tank line is below 50 bar. Startup shock can be reduced by the B15 throttle insert that narrows port P to 1.5 mm, giving finer control. These characteristics provide dependable directional control in compact hydraulic manifolds.
