If the schematic calls out spool symbol E, the replacement valve has to match it exactly. This size 32 valve brings symbol E, 520 l/min nominal flow at 350 bar, an integrated pressure reducing valve and a 4 to 20 mA current command.

Spool symbol E together with an external pilot oil return is a combination frequently required in established plants. The 4WRZE32E520-7X/6EG24EK31/F1D3M meets it, works at 520 l/min under pressures up to 350 bar and keeps pilot pressure steady through a built-in pressure reducing valve.
Benefits
- Spool symbol E with 3 switching positions across 4 ports keeps the existing hydraulic schematic valid.
- Nominal flow of 520 l/min within a maximum flow of 1600 l/min in size 32.
- Internal pilot oil supply with external return suits tank lines that carry back pressure.
- A 4 to 20 mA command is immune to voltage drop on long cables, supply 24 VDC.
- UKCA conformity documented, weight 43.68 kg, mounting pattern ISO 4401-10-09-0-05.
