4WE6E67-6X/EG24N9K4/T06

The 4WE6E67-6X/EG24N9K4/T06 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation circuits that require reliable on/off flow control. It is energized by a nominal voltage of 24 V DC, so it interfaces directly with standard machine control power rails. A nominal power draw of 30 W keeps the coil temperature within design limits while delivering enough magnetic force to shift the spool. The rated current of 1.25 A fits common PLC output modules without additional relays. Because the solenoid is specified for a 100 % ED duty cycle, it may remain continuously activated during extended machine cycles. The maximum permissible coil surface temperature of 120 °C defines the thermal boundary for safe operation in warm ambient environments. Wiring is made through a K4 connector according to DIN EN 175301-803, which supports quick replacement in the field. An IP65 protection class seals the electrical housing against dust ingress and low-pressure water jets.

The valve body is built to size 6 dimensions, giving it a compact footprint that matches ISO subplates for machines with limited space. Its porting pattern follows ISO 4401-03-02-0-05, allowing direct mounting on standardized manifolds without adapters. Pressure limits are set at 350 bar on ports a, b, and p, permitting use in high-pressure supply lines, while the tank port may see up to 210 bar, ensuring safe return flow management. A maximum flow capacity of 80 l/min lets the component handle medium-speed actuator movements without excessive pressure loss. To protect internal clearances, the hydraulic fluid cleanliness must meet ISO 4406 class 20/18/15. Precise positioning is aided by minimum control spool play, coded T06, which reduces shift hysteresis during rapid cycling. When electrical power is unavailable, operators can use the concealed manual override N9 to shift the spool for maintenance tasks. These design points combine to deliver stable directional control in demanding industrial hydraulics.
