Proportional Directional Valve 4WRTEM16E1-150L-4X/6EG24K31/F1M - Bosch Rexroth R901574862

A closed loop valve only brings its accuracy to the axis if the command transmission is clean as well. The 4WRTEM16E1-150L therefore works from a 4...20 mA current signal and holds the main spool at 150 l/min nominal through internal position feedback. Its pilot circuit is supplied externally at X and drained at Y, which keeps stroke time independent of working pressure.

Benefits

• Command value 4...20 mA, interference-proof even over long runs across a plant.
• Internal main spool position feedback, linear characteristic with spool symbol E1.
• 150 l/min nominal flow, limit 460 l/min at 350 bar.
• External pilot supply and external drain for consistent stroke times.
• On-board electronics, 24 VDC supply, 7-pole connector to EN 175201-804.
• Sturdy build at 14.04 kg valve weight, port pattern ISO 4401-07-07-0-05.

Applications

The valve is used on positioning and force control axes in machine tools, test rigs and forming plants. External pilot supply lets the main spool be moved even when the working circuit is unpressurised, for example while setting up the machine. The subplate must carry the X and Y channels.
