Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900953854
When no separate pilot circuit is available, this valve supplies itself. The 4WRZ32E1-520-7X takes pilot oil internally and releases it internally, passes 520 l/min nominal flow and works with spool symbol E1.

Description
Without a separate pilot circuit the valve has to draw its pilot pressure from the main circuit itself. This size 32 version has internal pilot oil supply and internal pilot oil return, handles 520 l/min nominal flow and limits pilot pressure through an integrated pressure reducing valve.
Benefits
- Internal pilot oil supply and internal pilot oil return, no extra control circuit required
- 520 l/min nominal flow, up to 1600 l/min across the valve
- An integrated pressure reducing valve limits pilot pressure at 350 bar system pressure
- Spool symbol E1, ISO 4401-10-09-0-05 port pattern
- Concealed auxiliary actuation, FKM seals, weight 44.26 kg
Applications
The valve suits compact power units that serve one large axis without a pilot circuit of their own. It is driven by external amplifier electronics at 24 VDC. Four ports and three switching positions cover the usual cylinder duties.
