Proportional Directional Valve 4WRZE32E520-7X/6EG24EK31/F1D3M - Bosch Rexroth R901137790

Spool symbol E together with an external pilot oil return is a combination frequently required in established plants. The 4WRZE32E520-7X/6EG24EK31/F1D3M meets it, works at 520 l/min under pressures up to 350 bar and keeps pilot pressure steady through a built-in pressure reducing valve.

Benefits

• Spool symbol E with 3 switching positions across 4 ports keeps the existing hydraulic schematic valid.
• Nominal flow of 520 l/min within a maximum flow of 1600 l/min in size 32.
• Internal pilot oil supply with external return suits tank lines that carry back pressure.
• A 4 to 20 mA command is immune to voltage drop on long cables, supply 24 VDC.
• UKCA conformity documented, weight 43.68 kg, mounting pattern ISO 4401-10-09-0-05.

Applications

The valve is installed in presses, rolling mills and large test rigs with high flow demand. An external pilot oil return is mandatory wherever return filters or coolers build up back pressure in the tank gallery. The valve runs on mineral oil of class HL with NBR seals.
