Proportional Directional Valve 4WRKE25R3-220L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R901259591

In a retrofit what counts most is how little has to change on the hydraulic manifold. The 4WRKE25R3-220L-3X/6EG24ETK31/A1D3M runs internal pilot oil supply and return, so only the four main ports are needed, and meters 220 l/min nominal flow from a ±10 V command.

Benefits

• Internal pilot oil routing in both directions, only four ports are used
• Spool symbol R3 with a closed mid position for loaded axes
• 220 l/min nominal flow, operating pressure up to 350 bar
• On-board electronics, ±10 V command value, 24 VDC supply
• Linear characteristic curve, flow follows the command without a step

Applications

Useful wherever an older axis is converted to proportional control and the existing manifold has to stay. Three switching positions and four ports match the usual cylinder circuit. NBR seals for hydraulic fluid HL.
