Proportional Directional Valve 4WRKE25E1-350L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R901043647

Compact control manifolds rarely leave room for X and Y lines. In version ETK the 4WRKE25E1-350L-3X therefore works entirely on internal pilot oil and needs only P, T, A and B on the manifold, at 350 l/min nominal flow and up to 350 bar operating pressure. The command value comes as a ±10 V voltage.

Benefits

• Internal pilot oil supply and internal pilot oil return, no X or Y line
• 350 l/min nominal flow, flow rate up to 870 l/min
• ±10 V command value, 24 V DC supply, 7-pole connector (6 + PE)
• Operating pressure up to 350 bar, spool symbol E1
• 17.75 kg weight, ISO 4401-08-08-0-05 connection diagram

Technical data

Applications

It pays off on densely populated manifolds in presses, lifting gear and test rigs. The tank line has to stay largely free of back pressure so the pilot stage can drain cleanly. Three switching positions allow controlled travel in both directions.
