Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9ETK31/A1V - Bosch Rexroth R901208876

The fewer external lines a manifold needs, the simpler the installation. The 4WRZE32E1-520-7X/6EG24N9ETK31/A1V works with internal pilot oil supply and internal pilot oil return, so no separate pilot plumbing is required, at 520 l/min nominal flow and 350 bar operating pressure.

Benefits

• Internal pilot oil supply and internal pilot oil return - no additional pilot lines on the manifold.
• 520 l/min nominal flow, up to 1600 l/min maximum, 350 bar operating pressure.
• Spool symbol E1, three switching positions, four ports, ISO 4401-10-09-0-05 mounting pattern.
• ±10 V command value into the on-board electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals for HL fluid, concealed manual override, weight 43.6 kg.

Applications

Fully internal pilot routing suits compact manifolds in presses, injection moulding machines and test benches whose tank line stays largely unloaded. With no pilot lines led outside, the number of fittings and therefore of potential leak points drops.
