The 4WRKE16W6-200L-3X/6EG24ETK31/A1D3M is produced by Bosch Rexroth for the 4WRKE Directional Valves series and serves to regulate flow direction and magnitude in hydraulic automation circuits. The nominal size 16 allows integration into medium-capacity subplates, while the ISO 4401-07-06-0-94 porting pattern aligns the body with standardized mounting faces. A nominal flow rating of 200 L/min at a 10 bar differential gives designers a clear baseline for system throughput, and a maximum main valve flow of 460 L/min accommodates short-term peaks without throttling. The valve withstands operating pressures up to 350 bar so it can be installed on high-pressure supply lines. Its characteristic curve form L offers a linear relationship between spool position and flow to simplify control tuning. An analogue signal interface enables proportional commands from common controllers, and the electronics operate from a 24 V DC supply found in most industrial panels.
The unit accepts a ±10 V command and feedback range, allowing precise closed-loop position control with standard servo amplifiers. A maximum supply current draw of 1.5 A defines the output capacity required from the drive card, and a 72 W power rating informs enclosure heat calculations. Electrical connection is achieved through a DIN EN 175201-804 plug so wiring follows a familiar pin layout. The housing carries an IP65 protection class, guarding internal components against dust ingress and low-pressure water jets on exposed machinery. Internal pilot oil supply removes the need for an external pilot line, and internal pilot oil drain routes leakage directly back to the tank passage to reduce external plumbing. A weight of 11.2 kg requires secure mounting support yet remains light enough for manual handling during installation.
