Proportional Directional Valve 4WRGE10V50L-1X/315G24EK31/A1M - Bosch Rexroth R901038772

Where a plant return line sits under back pressure, an internally relieved pilot circuit runs badly. This build of the size 10 range solves that with an external pilot oil return on an internal supply, 50 l/min nominal flow and operating pressure up to 315 bar.

Benefits

• External pilot oil return keeps the control circuit clear of back pressure in a shared return header.
• Internal supply saves the separate pilot feed line.
• 50 l/min nominal flow against a range maximum flow of 170 l/min.
• Spool symbol V, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• ±10 V command value at the on-board electronics, 24 VDC supply, mass 12.5 kg.

Technical data

Applications

The variant belongs in plants with a shared return header, filter section or cooler, such as press lines plus larger power units. Drain oil is routed separately back to tank. At 50 l/min the axis stays finely controllable, the seals are NBR.
