The 4WRKE16W8-200L-3X/6EG24ETK31/A5D3M proportional directional valve is produced by Bosch Rexroth for the 4WRKE Directional Valves series and is intended to meter and reverse hydraulic flow in automated machinery. It is built to the nominal size 16 envelope and delivers a nominal flow of 200 L/min, enabling precise control of medium-capacity actuators. Operating pressure at ports p, a, and b reaches 350 bar, supporting high-load circuits, while the pilot stage tolerates up to 315 bar. A linear characteristic curve marked “L” provides predictable spool travel, and hysteresis does not exceed 1 %, which stabilizes commanded positions. The integrated electronics accept a ±10 V command and actual feedback signal and are powered from a +24 V DC supply that draws a maximum of 72 W. Pilot oil is supplied and drained internally so no external pilot lines are required, reducing installation complexity.
The valve mounts on subplates that follow the ISO 4401-07-06-0-94 porting pattern, and electrical connection is made with a DIN EN 175201-804 plug to simplify field wiring. An IP65 protection class shields the housing against dust and water spray when the connector is properly sealed, and NBR seals provide compatibility with standard mineral hydraulic fluids. The main stage requires fluid cleanliness no worse than ISO 4406 class 20/18/15 to maintain spool accuracy and service life. Total mass is 11.2 kg, allowing the unit to be fastened securely to a manifold without additional supports. Together, these interface, sealing, and cleanliness features allow the valve to integrate reliably into closed-loop hydraulic automation systems that demand consistent flow control and robust environmental resistance.
