The 4WRKE16E-200L-3X/6EG24EK31/A1D3M valve is produced by Bosch Rexroth for the 4WRKE Directional Valves series, where it directs and meters hydraulic flow in automated machinery. The valve delivers a nominal flow of 200 L/min at a 10 bar differential to move actuators at controlled speeds. Ports p, a, and b tolerate up to 350 bar, enabling use in high-pressure circuits. Its pilot stage uses an internal oil supply with an external drain to keep return pressures low, and the pilot supply may reach 315 bar while port Y is restricted to 10 bar static. An ISO 4401-07-06-0-94 mounting pattern allows direct installation on standard subplates. NBR seals are fitted for compatibility with common mineral oils, and the assembled unit weighs 11.2 kg so one person can position it during service.
A proportional removable coil provides actuation and is powered from a 24 V DC source that draws no more than 1.5 A. The electronics accept a ±10 V command and feedback signal pair for closed-loop control. Spool movement shows a response sensitivity within 0.5%, and hysteresis is limited to 1%, supporting repeatable positioning. A DIN EN 175201-804 connector consolidates power and signal wiring, and the housing carries an IP65 rating that resists dust and water spray when the plug is secured. These electrical features, combined with the hydraulic characteristics noted earlier, give the valve stable performance across varying load conditions.
