Where the manifold already provides a controlled pilot pressure, a second pressure reducing valve inside the valve is redundant. This size 32 version does without it, meters 520 l/min nominal flow at up to 350 bar and works with spool symbol E1.

Total price
A pilot circuit whose pressure is limited anyway needs no second pressure reducing stage in the valve. The 4WRZE32E1-520-7X/6EG24N9EK31/A1M is built without that stage and meters 520 l/min nominal flow at an operating pressure of up to 350 bar.
Benefits
- Version without pressure reducing valve in the pilot stage, matched to an already controlled pilot pressure
- 520 l/min nominal flow in size 32, up to 1600 l/min with the corresponding pressure drop
- Internal pilot oil supply with external return, spool symbol E1 with three switching positions
- Command value ±10 V on the on-board electronics, concealed manual override
- 39 kg weight, NBR seals for HL hydraulic fluid, UKCA to SI2016/1091
