4WRKE16W6-200L-3X/6EG24TK31/A5D3M

The 4WRKE16W6-200L-3X/6EG24TK31/A5D3M directional valve belongs to the 4WRKE Directional Valves series and is produced by Bosch Rexroth for hydraulic automation where electrically operated spool positioning regulates flow and pressure. The valve accepts a ±10 V command input so a control amplifier can set spool displacement proportionally, and its maximum response sensitivity of 0.5 % enables small adjustments to be translated into stable flow changes. Hysteresis is limited to 1 %, reducing deviation between command and actual spool position during repeated cycles. With a nominal flow of 200 L/min at a 10 bar differential it meets medium-capacity circuit demands, while a maximum main valve flow of 460 L/min provides extra margin for peak conditions. The main ports withstand operating pressures up to 350 bar, supporting high-pressure mobile or industrial circuits. Installation follows the ISO 4401-07-06-0-94 mounting pattern, allowing direct fit onto standardized subplates. An IP65 protection class shields internal electronics from dust and low-pressure water jets encountered in machine environments.

The internal pilot stage draws 8.5 L/min of oil to shift the main spool, and the pilot supply may be pressurized up to 315 bar so the valve can function on the same high-pressure line as the actuators. A 24 V DC supply energizes the integrated electronics, and the design limits continuous supply current to 1.5 A to keep heat generation within acceptable levels. Peak electrical stress is handled through an impulse load rating of 3 A, preventing damage during rapid command changes. Power consumption does not exceed 72 W, which simplifies cabinet sizing for power supplies. A ±10 V measurement output sends the actual spool feedback to the controller for closed-loop operation. The assembled unit weighs 11.2 kg, supporting rigid mounting without special bracing while remaining manageable for maintenance staff.
