4WRKE35W8-1000L-3X/6EG24EK31/A1D3M

The 4WRKE35W8-1000L-3X/6EG24EK31/A1D3M directional valve belongs to the 4WRKE Directional Valves series and is manufactured by Bosch Rexroth for proportional control of flow and direction in hydraulic automation circuits. Its nominal size of 35 establishes passage dimensions that support a nominal flow of 1000 L/min while maintaining precise metering. A linear spool characteristic in combination with the W8 spool type lets the actuator vary output smoothly from zero to full stroke, providing consistent response to command signals. The valve tolerates a maximum operating pressure of 350 bar and can pass up to 3000 L/min during short-duration transients, making it suitable for large presses or die-casting machines. Porting pattern ISO 4401-10-08-0-94 simplifies mounting on standardized subplates. Internal pilot oil supply eliminates an external feed line, and an external pilot oil drain removes pilot fluid without pressurizing the main return. NBR seals contain system fluid under dynamic conditions.

For electrical integration, the valve accepts a 24 V DC supply and processes a ±10 V interface signal, permitting direct connection to motion controllers that issue symmetrical commands for noise immunity. The coil terminals follow DIN EN 175201-804; this coding establishes fixed pin assignments and mechanical keying so wiring errors are unlikely during service. When the mating connector is latched, the assembly attains an IP65 protection class, blocking dust and low-pressure water jets that are common on production lines. An integrated pressure reducing valve, type ZDR 6 DP0-4X/40YM-W80, keeps the pilot stage at a consistent reference pressure, allowing the main spool to track input signals even as system pressure varies. Total mass is 34 kg, so the supporting manifold or frame must be rigid enough for accurate alignment and to withstand vibration. Combined, these electrical and hydraulic elements enable reliable high-flow regulation in harsh industrial environments.
