Proportional Directional Valve 4WRTE25W8-220L-4X/6EG24ETK31/A1M - Bosch Rexroth R900954297
A mid-size cylinder does not need 350 l/min, it needs fine resolution at 220 l/min. This size 25 4WRTE works with internal pilot oil supply and internal return and follows a ±10 V command value through spool symbol W8.

Description
An oversized valve controls poorly at low speeds. With 220 l/min nominal flow at 350 bar this pilot-operated proportional directional valve in size 25 covers the middle power range, and pilot oil flows in and out internally.
Benefits
- 220 l/min nominal flow gives finer resolution on mid-size cylinders than the 350 l/min version.
- Internal pilot oil supply and internal return, no additional X or Y line needed.
- 350 bar operating pressure, flow up to 870 l/min through size 25.
- ±10 V command value, on-board electronics with internal spool position feedback.
- Spool symbol W8, 3 switching positions, 17.94 kg installed weight.
Applications
Fits feed axes on machine tools, lifting tables and plastics machinery with mid-size cylinders. Fully internal pilot oil routing shortens commissioning because only P, A, B and T have to be piped. Connection diagram ISO 4401-08-08-0-05.
