Proportional Directional Valve 4WRZ16W8-180-7X/6EG24N9TK4/M - Bosch Rexroth R901479623
When the main channel runs unpressurised at times, pilot oil has to come from outside. The 4WRZ16W8-180-7X/6EG24N9TK4/M uses external pilot supply with internal return and controls 180 l/min nominal flow at 350 bar maximum operating pressure.

Description
The pilot-operated 4WRZ16W8-180-7X/6EG24N9TK4/M proportional directional valve controls flow direction and rate steplessly. Pilot oil is supplied externally and returned internally, and the valve works without a pressure reducing valve of its own.
Benefits
- External pilot oil supply, internal pilot oil return
- Without pressure reducing valve, pilot pressure comes from the external supply
- Nominal flow 180 l/min, flow up to 460 l/min
- Spool symbol W8, 3 switching positions, 4 ports
- Maximum operating pressure 350 bar, size 16, weight 12.56 kg
- Electrical with external electronics, connector 7-pole (6 + PE) to EN 175201-804
Applications
Fits axes with stepless speed setting whose power unit carries a pilot pressure supply. The concealed auxiliary actuation helps during commissioning. An external amplifier card drives the valve.
