Proportional Directional Valve 4WRKE10W6-50L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901217997

At 50 l/min nominal flow in size 10 the pilot stage decides the response. In the 4WRKE10W6-50L-3X/6EG24EK31/F1D3M it is built as internal pilot oil supply, external pilot oil return, and the main spool works 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 internally and returned externally in the pilot stage.
• Operating pressure to 315 bar, throughput to 170 l/min, hydraulic fluid HL.
• 8.36 kg weight, 24 VDC supply voltage, NBR seals.

Technical data

Applications

The valve is used in position and force control loops on machine tools, presses and test rigs. 50 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.
