The 4WE6J6X/EG110NK4 valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where controlled flow direction is required. A continuous duty cycle of 100 % ED allows the coil to remain energized without time-based derating, supporting round-the-clock machine operation. The solenoid is designed for a 110 V DC supply, and a voltage tolerance of ±10 % keeps actuation reliable when supply levels vary. At that voltage the coil draws 0.25 A, so electrical power consumption remains close to the 30 W nominal rating. A DIN EN 175301-803 three-pole plug with protective earth simplifies field wiring and maintenance. The IP65 protection class seals the housing against dust and water jets, permitting installation in industrial wash-down zones. Coil insulation is rated so that its outer surface may reach 120 °C without loss of function, giving thermal headroom in hot manifolds.
The valve mounts on subplates using the NFPA T3.5.1 D03 interface, and its porting follows ISO 4401-03-02-0-05 so interchangeable stack designs are possible. Hydraulic ports p, A, and B withstand operating pressures up to 350 bar, while the tank port handles 210 bar, enabling use in high-pressure return circuits. A maximum flow of 80 l/min defines the throughput the spool can pass without excessive pressure drop. Switching events can occur at 4.2 cycles per second under direct current energization, giving adequate response for medium-speed actuators. A manual override is included and may be used when tank pressure does not exceed 50 bar, allowing service moves during power loss. Together these limits establish the valve’s capability for demanding hydraulic service where compact D03 components must deliver consistent performance.
