Description
A dedicated control oil circuit lets pilot pressure and working pressure be sized separately. The 4WRZE10W8-85-7X/6EG24N9K31/A1D3V uses that layout at 85 l/min nominal flow and 315 bar operating pressure.
Benefits
- External pilot supply and external return - pilot pressure freely selectable.
- 85 l/min nominal flow, 170 l/min peak throughput.
- ±10 V setpoint, on-board electronics, no external amplifier card required.
- Spool symbol W8, 3 switching positions, 4 ports, mass 8.49 kg.
- FKM seals for HL fluid, UKCA conformity to SI2016/1091.
Applications
Matches installations running a central control oil network, such as larger press lines or test fields with several axes. A separate control circuit allows response time to be tuned through pilot pressure.
Manufacturer
Bosch Rexroth lists this valve under material number R900964180, type code 4WRZE10W8-85-7X/6EG24N9K31/A1D3V. Characteristic curves, performance limits and installation dimensions are documented in datasheet RE 29115, the range overview in RE 07600-B.
