The 4WE6X7-6X/EG48N9K4/62 is a directional spool valve in the WE Directional Spool Valves series from Bosch Rexroth, used to route pressurized fluid in automated hydraulic systems. It follows the ISO 4401-03-02-0-05 porting pattern, allowing direct mounting on standardized subplates. The spool withstands 350 bar on ports P, A, and B while port t is limited to 210 bar, making the unit suitable for high-pressure supply lines and lower-pressure returns. An allowable flow of 80 l/min sets the throughput ceiling for connected actuators. The solenoid is rated for 48 V DC and draws 0.66 A so power supplies can be sized with minimal reserve. Nominal power consumption is 30 W, and a voltage tolerance of ±10 % lets the coil operate reliably despite minor supply variation. An IP65 housing on the K4 connector keeps dust and water jets out during industrial wash-downs.
The valve supports a 100 % duty cycle, so continuous energization does not require off-time for cooling. It can switch up to 4.2 times per second on direct current, enabling rapid directional changes in servo loops. A concealed N9 manual override lets technicians shift the spool mechanically when electrical power is unavailable. Wiring is made through a DIN EN 175301-803 K4 plug that matches common control-cabinet connectors. Insulation class F permits winding temperatures up to 155 °C, extending coil life under elevated ambient heat. A locating hole for an ISO 8752-3x8-St spring pin helps align the valve accurately on the mounting plate, as denoted by the /62 suffix. System oil must meet ISO 4406 20/18/15 cleanliness to protect the precision-fit spool from abrasive wear.
