The 4WE6D6X/OFEG24N9K4/B15 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It routes hydraulic oil between pressure, work, and return ports to automate cylinder or motor movement. Its nominal size 6 establishes the mounting footprint for sandwich or subplate installation, and the ISO 4401-03-02-0-05 porting pattern aligns the valve with standardized manifolds. A P-port orifice diameter of 1.5 mm regulates inlet flow and helps stabilize upstream pressure. The valve passes up to 80 l/min under direct-current operation, while the pressure rating of 350 bar on P, A, and B ports supports high-load circuits. The T port withstands 210 bar, preventing case drain damage during back-pressure events. A wet-pin detachable coil solenoid allows quick field replacement and uses hydraulic fluid for heat transfer, and a 30 W nominal power draw minimizes panel supply requirements.
The actuation variant with a detent mechanically locks the spool in its last energized position, which maintains flow direction after power removal. A 100 % ED duty cycle permits uninterrupted coil energization without overheating. The coil is designed for 24 V DC operation, and a ±10 % voltage tolerance keeps performance stable despite supply fluctuations. Electrical connection is made through a DIN EN 175301-803 plug, giving rapid assembly with industry-standard cable harnesses; this interface also seals against moisture when mated with the recommended gasket. A concealed manual override lets maintenance staff shift the spool during commissioning while preventing accidental activation in service. The enclosure carries an IP65 ingress rating so dust and water jets cannot reach internal components in typical industrial environments.
