Proportional Directional Valve 4WRZE32E520-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R901119511

At 520 l/min the main spool moves a lot of oil, so pilot pressure has to stay stable. This variant supplies the pilot stage internally and routes pilot oil to tank through its own line, clear of system return pressure. Spool symbol E, size 32, a 1600 l/min ceiling and 350 bar operating pressure.

Key benefits

• 520 l/min nominal flow in size 32, up to 1600 l/min
• Internal pilot supply with external drain, stable pilot stage even with tank back pressure
• Spool symbol E, 3 switching positions, 4 ports
• 4 to 20 mA command value, on-board electronics, 24 VDC on a 7-pole connector (6 + PE)
• 350 bar operating pressure, subplate mounting to ISO 4401-10-09-0-05
• 44.1 kg weight, FKM seals for HL hydraulic fluid

Applications

Valves like this run the main axes of large presses, forging equipment and test rigs. Where the return passes a filter and a cooler, the external pilot drain stops pilot pressure from drifting. Concealed auxiliary actuation stays available for service work.
