Proportional Directional Valve 4WRZ10W8-25-7X/6EG24N9K4/M - Bosch Rexroth R900717638
Small cylinders call for a small nominal flow, otherwise the axis is already at full speed after the first tenth of the command signal. The 4WRZ10W8-25-7X works at 25 l/min nominal flow and 315 bar and takes its pilot oil externally.

Description
Fine metering starts with the choice of flow rating. The 4WRZ10W8-25-7X/6EG24N9K4/M carries a 25 l/min nominal flow and therefore spreads the command range over a long control travel in size 10.
Benefits
- 25 l/min nominal flow, sized for small cylinders and slow feed motion.
- Spool symbol W8, 3 switching positions, subplate mounting on ISO 4401-05-05-0-05.
- Pilot oil in and out externally, the pilot circuit is supplied on its own.
- 315 bar operating pressure at 7.74 kg, NBR seals for HL hydraulic fluid.
- Concealed manual override, commanded from 24 VDC through external electronics.
Applications
Valves like this sit on adjusting and infeed axes, on test rigs with small cylinders and on clamping systems where a quiet start matters. The low nominal flow spreads the usable control range across the whole command signal and makes low speeds repeatable. Size and hole pattern stay the same as on the higher flow ratings of the series.
