In systems with a dedicated pilot pump the pilot oil has to come from outside. This 4WRKE with spool symbol W6 takes it externally and drains it externally, converts 400 l/min nominal flow at 350 bar and follows a ±10 V voltage setpoint.

Total price
Where a separate pilot pump is already installed, the main valve should not tap the working circuit. The 4WRKE32W6-400P-3X/6EG24K31/A1D3M is built for that: external pilot oil supply, external pilot oil return, 400 l/min nominal flow in size 32 and a ±10 V command value.
Benefits
- The external pilot circuit keeps control pressure independent of working pressure up to 350 bar.
- 400 l/min nominal flow, maximum flow 1550 l/min.
- ±10 V command value on 24 VDC, direction and magnitude in one signal.
- Linear characteristic curve with fine control range for a soft start on heavy masses.
- NBR seals, ISO 4401-10-09-0-05 interface, 37 kg.

Applications
It is typically found in presses and lifting gear whose power unit brings its own pilot supply. The external return carries pilot oil to tank without back pressure, which keeps response times stable even when tank pressure is high. The interface follows size 32 to ISO 4401-10-09-0-05.
Manufacturer
Bosch Rexroth, material number R901484614. The type code 4WRKE32W6-400P-3X/6EG24K31/A1D3M differs from the internally piloted version in the pilot circuit and in the ±10 V command value.
