Proportional Directional Valve 4WRZ32E520-7X/6EG24N9K4/M - Bosch Rexroth R900719696
A large axis at 520 l/min with a pilot stage that neither draws oil from the main channel nor relieves into it. The 4WRZ32E520-7X/6EG24N9K4/M is built exactly that way, is rated at 350 bar and weighs 42.96 kg.

Description
Separating main and pilot circuit makes fault finding and pilot pressure sizing easier. The 4WRZ32E520-7X/6EG24N9K4/M uses external supply and external drain for that, at 520 l/min nominal flow with spool symbol E.
Benefits
- Pilot oil fed in and drained externally, main and pilot circuit kept apart.
- 520 l/min nominal flow, flow up to 1600 l/min.
- 350 bar maximum operating pressure, ISO 4401-10-09-0-05 pattern.
- Spool symbol E, three switching positions, concealed auxiliary actuation.
- 42.96 kg weight, NBR seals, external electronics at 24 VDC.
Applications
The valve serves presses, stretching lines and large test benches with a pilot circuit of their own. The clear separation eases commissioning and diagnosis. For a swap, the routing of the pilot oil decides alongside the mounting pattern.
