Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9K31/F1V - Bosch Rexroth R901035809

Large axes need 520 l/min, and the signal cable that reaches them is rarely short. The 4WRZE32W8-520-7X/6EG24N9K31/F1V puts both together: the full nominal flow of size 32 with a 4 to 20 mA command value, plus external pilot oil supply and external pilot oil return for systems with their own pilot station.

Benefits

• 520 l/min nominal flow and up to 1600 l/min maximum at 350 bar operating pressure.
• 4 to 20 mA command value stays stable over long cable runs and in electrically noisy surroundings.
• External pilot oil supply and external pilot oil return, independent of pressure in the tank line.
• Spool symbol W8, three switching positions, four ports, subplate mounting to ISO 4401-10-09-0-05.
• On-board electronics at 24 VDC, 7-pole connector (6 + PE) to EN 175201-804, FKM seals, 43.4 kg.

Applications

Intended for main axes in presses, rolling mills and large test benches whose controllers provide current outputs. If the same axis is later resized, the 360 l/min variant of the series fits the identical manifold interface.
