The 4WE6D6X/EG24K72L/B10/62 valve is built by Bosch Rexroth within the WE Directional Spool Valves series to shift hydraulic flow paths in automated circuits. Its solenoid is rated for 24 V DC so control panels can use standard low-voltage supplies, and power draw is limited to 30 W to restrict heat production. Class F coil insulation lets the winding endure higher temperatures, while a 100 % ED (S1) duty cycle keeps the valve energized continuously when required. Coil surface temperature may reach 120 °C, meaning surrounding parts must tolerate that heat. Switch-off overvoltage is limited to 500 V to shield driver electronics from inductive spikes, and a voltage tolerance of ±10 % maintains reliable actuation despite supply fluctuation. A maximum switching frequency of 4.2 cycles per second supports rapid machine sequencing.
The valve carries up to 80 l/min of hydraulic fluid under direct-current control, giving medium-size actuators adequate flow. Operating pressure reaches 350 bar on ports P, A, and B, and port T withstands 210 bar so return lines can tolerate elevated back-pressure. A 1.0 mm throttle insert in port P moderates pressure surges, and system oil must meet ISO 4406 cleanliness class 20/18/15 to avoid spool sticking. Mounting follows the NFPA D03 interface with the ISO 4401-03-02-0-05 porting pattern, ensuring interchange with common subplates. A locating hole with a locking pin provides precise alignment during installation, completing the mechanical features needed for dependable hydraulic automation.
