Proportional Directional Valve 4WRZ10E1-25-7X/6EG24N9TK4/D3M - Bosch Rexroth R901322981
Fine positioning only works when the nominal flow is small enough. The 4WRZ10E1-25-7X/6EG24N9TK4/D3M works with a 25 l/min nominal flow in size 10 and still withstands 315 bar operating pressure. Pilot oil arrives externally and returns internally, at 8.22 kg.

Description
Small movements need a fine characteristic, not much flow. The 4WRZ10E1-25-7X/6EG24N9TK4/D3M works at 25 l/min nominal flow in size 10 and controls up to 315 bar.
Benefits
- 25 l/min nominal flow for fine resolution of the spool position.
- 170 l/min maximum flow at 315 bar, headroom for fast travel.
- Spool symbol E1, 3 switching positions across 4 ports, subplate mounting ISO 4401-05-05-0-05.
- External pilot oil supply, internal return, with a pressure reducing valve in the pilot stage.
- 8.22 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.
Applications
The application is on axes that have to approach slowly and accurately, for instance on test benches and positioning units. The small nominal step improves the resolution of the command signal in the lower range. An external amplifier supplies the valve current and can sit centrally in the control cabinet.
Manufacturer
Bosch Rexroth, material number R901322981. Characteristic curves, step responses and installation dimensions are given in data sheet RE 29115 on the pilot-operated proportional directional valve, the series overview in RE 07600-B.
