4WRKE16E200L-3X/6EG24ETK31/A1D3M

The 4WRKE16E200L-3X/6EG24ETK31/A1D3M is a proportional directional valve manufactured by Bosch Rexroth within the 4WRKE Directional Valves series. It meters hydraulic flow in automation circuits that require precise position and velocity control. With a nominal size of 16, the housing fits mid-range manifolds and supports systems where space and flow balance are important. A nominal flow of 200 L/min establishes the baseline throughput so actuators can reach rated speed without excessive pressure drop. The valve follows a linear characteristic curve, which gives a predictable relationship between command signal and spool position for straightforward loop tuning. It accepts a ±10 V command and feedback signal so analog controllers can read and drive the spool directly. Response sensitivity is no greater than 0.5 percent, allowing small input changes to create measurable flow adjustments, while hysteresis is kept at or below 1 percent to reduce deadband during direction reversals. The solenoid section runs on a 24 VDC supply, keeping wiring compatible with standard machine voltage, and the electrical assembly draws up to 72 W, which defines cabinet power budgeting.

This model uses an ISO 4401-07-06-0-94 mounting interface, enabling drop-in installation on common subplates without custom drilling. The main stage handles operating pressures up to 350 bar, letting it work in high-pressure circuits, and the valve can pass up to 460 L/min when the spool is fully open so large cylinders shift rapidly. Pilot oil is supplied internally and drained internally, simplifying external plumbing and reducing leak points. The internal drain path must tolerate a maximum of 250 bar, aligning with pilot gallery limits in many manifolds. An ingress protection rating of IP65 shields the electrical connection against dust and low-pressure water jets, allowing placement near wash-down zones. The assembly weighs 11.2 kg, which factors into manifold support loads and handling during maintenance.
