Proportional Directional Valve 4WRZ25W8-220-7X/6EG24N9K4/D3V - Bosch Rexroth R900951702

If the pilot stage is to share neither pressure nor return with the working circuit, both paths are routed to the outside. The 4WRZ25W8-220-7X/6EG24N9K4/D3V is built that way and meters 220 l/min nominal flow with spool symbol W8.

Benefits

• External pilot oil supply and external return, separated from the working circuit
• Spool symbol W8, three switching positions, pressure reducing valve fitted
• Nominal flow 220 l/min, maximum flow 870 l/min
• Pilot-operated spool valve with concealed auxiliary actuation
• Maximum operating pressure 350 bar, FKM seals, weight 20.52 kg

Applications

Fits plants with their own pilot pressure station and a separate pilot oil return, such as large presses and test rigs. The pilot stage then stays untouched by load changes in the working circuit. Control through external electronics.
