The 4WE6H6X/EW230N9K4/ZV valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow to actuators in automated machinery. The valve follows the ISO 4401-03-02-0-05 mounting pattern, facilitating drop-in installation on standard subplates. Channels p, a, and b can be pressurized up to 350 bar, while port t is limited to 160 bar, allowing it to handle typical pressure stages in industrial circuits. The design supports a maximum flow of 60 l/min so actuators receive sufficient oil volume without excessive pressure loss. A 230 V AC supply at 50 or 60 Hz energizes the solenoid, and the coil accepts a ±10 % voltage variation for stable performance on imperfect mains. Switch-on power is 220 VA to build magnetic force quickly, after which holding power falls to 50 VA to limit heat. Continuous service is possible because the duty cycle is 100 % ED, and class H insulation protects the winding against elevated temperatures.
Electrical termination uses a plug conforming to EN 175301-803-A coded K4, giving a sealed connector that matches common machine wiring harnesses. The housing attains IP65, so dust and low-pressure water jets cannot reach internal components when the connector is fitted. A concealed manual override identified as version N9 lets maintenance staff shift the spool without electrical power. Dynamic sealing relies on FKM elastomers, which resist high-temperature hydraulic oils. The solenoid tube projects a clamping length of 22 mm for secure fastening under vibration. A mass of 1.95 kg for the two-solenoid configuration keeps the assembly light enough for compact manifolds. These features round out the hydraulic and electrical data presented earlier and align the valve with automated systems that require dependable directional control.
