Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900925737

Where a hydraulic axis has to follow an electrical command value steplessly, this pilot-operated proportional directional valve of the 4WRZE series does the work. It processes a 4...20 mA current command and meters 85 l/min nominal flow at a maximum operating pressure of 315 bar.

Benefits

• Current interface 4...20 mA, the on-board electronics evaluate the command value at the valve itself, supply 24 VDC
• 85 l/min nominal flow and 170 l/min maximum flow at 8.6 kg valve weight
• Built-in pressure reducing valve keeps the pilot pressure independent of system pressure, internal pilot oil supply and internal pilot oil return
• Spool symbol W6 with 3 switching positions and 4 ports for direction and speed of a double-acting cylinder
• FKM seals and HL hydraulic fluid, mounting pattern ISO 4401-05-05-0-05 for subplate mounting

Technical data

Applications

Typical installations are presses, injection moulding machines and test rigs where a cylinder has to ramp up and decelerate under control. Internal pilot oil supply requires that port P carries enough pressure for the pilot stage at all times. The concealed auxiliary actuation allows the spool to be moved during commissioning without a command signal applied. Conformity is declared as UKCA with electromagnetic compatibility to SI2016/1091.
