Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901310376

A manifold with no separate pilot lines plus no sensitive voltage signal is quicker to commission. The 4WRZE32E1-520-7X/6EG24N9ETK31/F1D3M takes its pilot oil internally, returns it the same way, then meters 520 l/min against a 4 to 20 mA command value.

Benefits

• Internal pilot oil supply with internal return saves both pilot lines on the manifold.
• 4 to 20 mA command value into the on-board electronics, 24 VDC supply, 7-pole connector (6 + PE).
• 520 l/min nominal flow at 350 bar, maximum flow of 1600 l/min.
• Symbol E1 with 3 switching positions, concealed manual override, pressure reducing valve in the pilot stage.
• 44.08 kg weight on the ISO 4401-10-09-0-05 interface, UKCA conformity to SI2016/1091.

Application

The version is meant for compact control manifolds in presses as well as test rigs that offer no separate pilot circuit. At 520 l/min it moves cylinders of very large bore within short cycle times. System pressure has to stay high enough to carry the pilot stage reliably.
