Proportional Directional Valve 4WRTE25V1-350P-4X/6EG24EK31/A1M - Bosch Rexroth R901271689

Short rapid traverse times on a closed-loop axis depend on the rated flow of the valve. In size 25 the 4WRTE25V1-350P-4X/6EG24EK31/A1M provides 350 l/min rated flow and keeps the main spool on the plus or minus 10 V setpoint through internal position feedback.

Benefits

• 350 l/min rated flow in size 25, maximum flow 870 l/min.
• Spool symbol V1, 3 switching positions, 4 ports, linear characteristic with a fine control range.
• Analog command value plus or minus 10 V into the on-board electronics, 24 VDC supply.
• Internal pilot oil supply, external pilot drain, maximum operating pressure 350 bar.
• Installed mass 17.86 kg, NBR seals, HL hydraulic fluid.

Applications

Typical mounting points are feed axes on forming machines, lifting gear and test cylinders that alternate between rapid traverse and controlled feed. The interface follows the ISO 4401-08-08-0-05 pattern, so a later change of rating needs no new subplate. Pilot oil is taken internally and drained externally through Y.
