The 4WE6H6X/EW110N9DK25/62 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow between actuators and pumps in automated machinery. As a 4/3-way spool unit with spool symbol H, it offers a center position that blocks all ports for load holding. The nominal size 6 format keeps the envelope compact while matching standard subplates. A maximum flow of 60 l/min supports medium-duty circuits, and the design withstands system pressures up to 350 bar while allowing the tank port to see 160 bar. Integration is simplified by the NFPA D03 mounting interface and the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability across manifold blocks.
The solenoid is energized with 110 V at either 50 or 60 Hz, drawing 0.52 A on 50 Hz supplies and 0.39 A on 60 Hz to shift the spool electrically. Insulation class H windings let the coil surface reach up to 120 °C without damage, and the IP65 housing prevents water jets and dust from affecting operation. A concealed N9 manual override enables local shifting when power is absent, and the assembly is secured to the valve body by an ISO 8752-3×8 locking pin to resist vibration. These electrical and mechanical details ensure dependable control of the directional element within automated hydraulic stations.
