The 4WE6H6X/EW110N9DK25/V/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. Intended to route hydraulic oil between service lines, it fits sub-plates with the ISO 4401-03-02-0-05 porting pattern for consistent manifold mounting. The valve handles a maximum operating pressure of 350 bar at ports P, A, and B, while port T is limited to 160 bar to protect the return circuit. Flow capacity reaches 60 l/min, enabling moderate throughput without cavitation. FKM sealing elements contain aggressive fluids and high temperatures common in industrial power units. Environmental protection is rated at IP65, so dust and water jets do not impair the energized coil or spool chamber. Reliable movement is maintained when the hydraulic fluid cleanliness is kept at ISO 4406 class 20/18/15. Assembly is aided by a locating hole equipped with an ISO 8752-3×8 locking pin that secures the body on the baseplate.
The integral solenoid is specified for 110 V AC at 50 or 60 Hz, drawing 0.52 A on a 50 Hz supply and 0.39 A on 60 Hz. An inrush demand of 220 VA shifts the spool, after which the circuit sustains position with 50 VA holding power. Continuous energization is possible because the coil is rated for a 100 % ED duty cycle, eliminating the need for cooling intervals. Voltage fluctuations of up to ±10 % are acceptable without loss of function, supporting installation on general plant power nets. Electrical termination is provided through a 5-pole DK25 central connector that simplifies quick replacement during maintenance. The molded connector body shields the contacts from shop contaminants, matching the valve’s overall suitability for automated hydraulic machinery.
