Proportional Directional Valve 4WRTE25E1-350L-4X/6EG24ETK31/A1M - Bosch Rexroth R900248714

A manifold without separate pilot lines saves drilled holes, fittings and assembly errors. The 4WRTE25E1-350L-4X/6EG24ETK31/A1M feeds its pilot stage internally and returns the pilot oil internally, at 350 l/min nominal flow with an operating pressure of up to 350 bar.

Benefits

• Internal pilot oil supply plus internal pilot oil return, the manifold needs no X or Y bore
• 350 l/min nominal flow on connection diagram ISO 4401-08-08-0-05, size 25 allows up to 870 l/min
• Operating pressure up to 350 bar across four ports with three switching positions
• Spool symbol E1 with a command value of ±10 V on the on-board electronics, spool position fed back internally
• 17.86 kg installed weight, NBR seals for HL hydraulic fluid, wiring through a connector, 7-pole (6 + PE) according to EN 175201-804

Technical data

Applications

Typical installations are presses, injection moulding machines and test rigs whose manifold carries pressure permanently, so it can feed the pilot stage as well. On plants that run depressurised at times, a version with external pilot supply is the sound choice. Mounting pattern ISO 4401-08-08-0-05 belongs to size 25 and fits existing blocks.
