Proportional Directional Valve 4WRTE27E500P-4X/6EG24ETK31/A1M - Bosch Rexroth R901025779
Where no separate pilot circuit exists, the valve has to supply itself. This size 27 unit draws pilot oil internally, returning it internally, at 500 l/min nominal flow with 270 bar. ±10 V command value, spool symbol E with a fine control range.

Description
Internal pilot oil supply together with internal pilot oil return leave this pilot-operated proportional directional valve in size 27 ready to bolt on with no X line or Y line, while it moves 500 l/min nominal flow at 270 bar operating pressure.
Advantages
- Pilot oil taken internally, returned internally, saving two lines in the manifold.
- 500 l/min nominal flow with up to 1000 l/min maximum flow.
- ±10 V command value at the on-board electronics on a 24 VDC supply.
- Linear characteristic with a fine control range for slow approach motion.
- 19.34 kg, NBR seals, HL hydraulic fluid, ISO 4401-08-07-0-05 pattern.
Applications
Intended for large presses, forging plants, retrofits where the existing manifold has no separate pilot galleries. System pressure must stay above minimum pilot pressure so the spool shifts reliably.
Manufacturer
