Proportional Directional Valve 4WRKE10W6-50L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R900749617

Where no separate pilot circuit is available at the installation point, the pilot version has to suit. The 4WRKE10W6-50L-3X/6EG24ETK31/F1D3M is set for internal pilot oil supply and return and regulates 50 l/min nominal flow with symbol W6.

Benefits

• Internal spool position feedback at 50 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 and returned internally in the pilot stage.
• Operating pressure to 315 bar, throughput to 170 l/min, hydraulic fluid HL.
• 8.4 kg weight, 24 VDC supply voltage, NBR seals.

Applications

Typical locations are feed and infeed axes in machinery plus control loops inside hydraulic power units. Spool symbol W6 determines how the ports relate to each other in the centre position. The on-board electronics take the command value from the higher-level controller directly.
