The 4WE6G73-6X/EG96N9K4/A12 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is installed to route oil flow in hydraulic automation circuits. It follows the ISO 4401-03-02-0-05 porting pattern so it fits standard NG6 subplates without adapter blocks. The valve handles a maximum operating pressure of 350 bar on pressure and working ports, which allows safe service in high-pressure systems. Its tank port withstands 210 bar, preventing damage when return lines carry elevated back-pressure. A rated flow capacity of 80 l/min provides adequate volume for medium-size cylinders and motors. With a switching frequency of 4.2 cycles per second in direct-current operation, the spool responds quickly to command signals while remaining mechanically stable.
The magnetic coil is designed for a nominal voltage of 96 V DC and draws 0.33 A, giving a nominal power input of 30 W for predictable heat generation. A voltage tolerance of ±10 % lets the unit operate without nuisance trips when supply levels fluctuate. Continuous energization is possible because the duty cycle is 100 ED, so no additional timers or cooling pauses are needed. Coil surface temperature may reach 120 °C, and the housing carries an IP65 rating to block dust and low-pressure water jets under that thermal load. Electrical termination is accomplished through a connector built to DIN EN 175301-803, ensuring compatibility with common mating plugs. A concealed manual override lets maintenance personnel shift the spool when power is absent, and it can be operated safely as long as tank pressure stays below 50 bar.
