Proportional Directional Valve 4WRKE10W6-100L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901256920

Where no separate pilot circuit is available at the installation point, the pilot version has to suit. The 4WRKE10W6-100L-3X/6EG24TK31/F1D3M is set for external pilot oil supply, internal pilot oil return and regulates 100 l/min nominal flow with symbol W6.

Benefits

• Internal spool position feedback at 100 l/min nominal flow.
• Linear characteristic curve between the command value 4...20 mA and orifice area.
• Symbol W6 in size 10, four ports, three switching positions.
• Pilot oil supplied externally and returned internally in the pilot stage.
• Operating pressure to 315 bar, throughput to 170 l/min, hydraulic fluid HL.
• 8.35 kg weight, 24 VDC supply voltage, NBR seals.

Applications

The valve is used in position and force control loops on machine tools, presses and test rigs. 100 l/min nominal flow suits mid-size cylinders whose axis has to follow the command continuously. On a subplate to ISO 4401-05-05-0-05 it replaces an equally wired proportional valve without reworking the piping.
