Proportional Directional Valve 4WRZE32W9-520-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901035089

This version is the standard build of the top flow rating: 520 l/min nominal flow, NBR seals for HL hydraulic fluid and 350 bar operating pressure. The pilot stage draws its oil internally and returns it externally, so the pilot return stays decoupled from the tank pressure of the system.

Key benefits

• 520 l/min nominal flow in size 32, flow ceiling 1600 l/min
• NBR seals, the standard set for HL hydraulic fluid
• 350 bar maximum operating pressure on connection diagram ISO 4401-10-09-0-05
• External pilot oil return decouples the pilot stage from system tank pressure
• Command value ±10 V at the on-board electronics, 24 VDC supply
• 44.08 kg weight, spool symbol W9 with 3 switching positions and 4 ports

Applications

Intended for presses and forming lines that fill a large cylinder quickly and still have to decelerate under control. The pressure reducing valve in the pilot stage keeps pilot pressure steady even when working pressure swings during the cycle. The concealed auxiliary actuation moves the main spool without electronics.
