Proportional Directional Valve 4WRTEM25E1-350L-4X/6EG24K31/A1M - Bosch Rexroth R901520855

A high nominal flow of 350 l/min meets external pilot supply with external drain here. The pilot stage therefore keeps its authority even when working pressure collapses. Flow limit is 870 l/min, operating pressure 350 bar.

Benefits

• 350 l/min nominal flow, 870 l/min flow limit at 350 bar
• External pilot oil supply plus external pilot drain, separated circuits
• Spool symbol E1 with 3 switching positions across 4 ports
• Analog command plus to minus 10 V, on-board electronics on 24 VDC
• NBR seals for HL fluid, mass of 18 kg

Applications

Plants lowering loads or working against changing counter forces need a pilot circuit with its own supply. That is what this variant is built for. At 350 l/min it also moves cylinders of large piston area briskly.
