Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9EK31/A1V - Bosch Rexroth R901235334

A size 32 main valve that has to work without an extra pilot pump still needs a clean path for its pilot drain. The 4WRZE32E1-520-7X/6EG24N9EK31/A1V combines internal pilot oil supply with external pilot oil return and delivers 520 l/min nominal flow at up to 350 bar.

Benefits

• Spool symbol E1, three switching positions across four ports, ISO 4401-10-09-0-05 mounting pattern.
• Internal pilot oil supply with external pilot oil return - no pilot power unit, yet an unloaded pilot drain.
• 520 l/min nominal flow, up to 1600 l/min maximum, operating pressure up to 350 bar.
• On-board electronics with ±10 V command value, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals, HL hydraulic fluid, concealed manual override.

Applications

The internal supply and external drain combination is used in presses, test rigs and forming lines whose shared tank line carries pressure. Subplate mounting to ISO 4401-10-09-0-05 keeps the valve interchangeable within the series, and the command signal comes from a controller voltage output.
