Proportional Directional Valve 4WRKE10E25L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901407220

At 25 l/min nominal flow in size 10 the pilot stage decides the response. In the 4WRKE10E25L-3X/6EG24EK31/F1D3M it is built as internal pilot oil supply, external pilot oil return, and the main spool works with symbol E.

Benefits

• Internal spool position feedback at 25 l/min nominal flow.
• Linear characteristic curve between the command value 4...20 mA and orifice area.
• Symbol E in size 10, four ports, three switching positions.
• Pilot oil supplied internally and returned externally in the pilot stage.
• Operating pressure to 315 bar, throughput to 150 l/min, hydraulic fluid HL.
• 8.36 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 E 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.
