Proportional Directional Valve 4WRZE32E1-520-7X/6EG24K31/A1M - Bosch Rexroth R901274144

When the main circuit is unloaded during a cycle, an internally supplied pilot stage loses its force. This version of the 4WRZE32E1-520-7X therefore draws pilot oil externally and returns it externally, at 520 l/min nominal flow and 350 bar.

Benefits

• External pilot oil supply and external return, keeping the pilot stage independent of main pressure.
• ±10 V command value, directly compatible with the analog outputs of common control cards.
• 520 l/min nominal flow and up to 1600 l/min maximum flow in size 32.
• 350 bar operating pressure, NBR seals, connection diagram ISO 4401-10-09-0-05.
• 43.32 kg weight with symbol E1, three switching positions and on-board electronics on 24 V DC.

Applications

The variant makes sense in systems with a dedicated control oil circuit, for instance presses running on accumulators or plants that unload the main circuit between strokes. Four ports and subplate mounting keep integration into existing manifolds straightforward.
