The 4WE6Y6X/EG24N9K4QMAG24/V directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery. The valve accepts a maximum operating pressure of 350 bar at the A, B, and P ports so it can be installed in high-pressure circuits. A maximum flow of 80 l/min determines the largest actuator speed it can supply. The coil is energized with 24 V DC and draws a rated current of 1.25 A, giving a nominal power consumption of 30 W. Continuous operation is possible because the duty cycle is 100%. The coil surface may reach 120 °C, which sets the thermal design limit for adjacent components. An ISO 4401-03-02-0-05 porting pattern allows direct mounting on standard subplates.
The hydraulic fluid must stay between −15 °C and +80 °C, ensuring proper viscosity and seal life. Ambient temperature around the valve may rise to +50 °C without derating. Acceptable fluid viscosity ranges from 2.8 to 500 mm²/s, which provides flexibility with different oil grades. A manual override can be used when tank pressure is below 50 bar, allowing emergency actuation during power loss. The T port withstands up to 210 bar, preventing case-drain damage in back-pressure conditions. The armature can shift up to 4.2 times per second, defining the maximum switching frequency for rapid cycling tasks. These characteristics, combined with the specifications presented earlier, support consistent spool control in demanding hydraulic automation systems.
