Proportional Directional Valve 4WRKE25E1-350P-3X/6EG24EK31/A1D3M - Bosch Rexroth R901072882

A shared tank line builds up back pressure that slows the pilot stage, and a dedicated pilot drain protects against exactly that. This size 25 valve takes pilot oil internally, discharges it externally and processes the ±10 V command value at 350 l/min nominal flow.

Benefits

• Internal pilot oil supply with external pilot oil return through the Y port
• ±10 V command value, 24 VDC supply, on-board electronics at the valve
• 350 l/min nominal flow, up to 870 l/min possible across the valve
• Spool symbol E1, linear characteristic curve with a fine control range
• NBR seals, operating pressure up to 350 bar, weight 17.83 kg

Applications

Typical cases are presses and test plants in which several consumers work into the same return line. Subplate mounting to ISO 4401-08-08-0-05 allows replacement without changing the manifold. HL is the intended hydraulic fluid.
