Proportional Directional Valve 4WRTE25V220P-4X/6EG24EK31/A1M - Bosch Rexroth R901212530

A positioning axis drawing around 200 l/min needs a valve that resolves the setpoint finely at the low end. The 4WRTE25V220P-4X/6EG24EK31/A1M meters 220 l/min rated flow with spool symbol V, whose characteristic carries a pronounced fine control range.

Benefits

• 220 l/min rated flow in size 25, maximum flow 870 l/min for short rapid traverse phases.
• Spool symbol V, linear with a fine control range, 3 switching positions across 4 ports.
• On-board electronics take the plus or minus 10 V command directly, with no amplifier card in the cabinet.
• Internal pilot oil supply, external pilot drain through Y, maximum operating pressure 350 bar.
• Installed mass 17.8 kg, NBR seals, HL hydraulic fluid.

Applications

The valve fits feed and positioning axes on machine tools, injection moulding machines and test rigs whose cylinders draw around 200 l/min. Internal spool position feedback holds the setting under changing load. A Y line has to be planned in the subplate for the external pilot drain.
