Proportional Directional Valve 4WRTEM16E1-150L-4X/6EG24EK31/F1M - Bosch Rexroth R901507401

A voltage command value loses meaning over 30 m of cable running next to a converter. This size 16 version therefore works with a 4...20 mA current command value and meters its 150 l/min nominal flow as steadily as it would on a short cable.

Benefits

• The 4...20 mA command value is immune to voltage drop and to interference picked up on long lines.
• Live zero at 4 mA separates a broken cable from a genuine zero command straight away.
• 150 l/min nominal flow at 350 bar, peak flow up to 460 l/min.
• Internal pilot oil supply with external pilot oil return, suited to tank lines carrying back pressure.
• Spool symbol E1, on-board electronics, weight 11.5 kg, interface ISO 4401-07-07-0-05.

Applications

This variant is preferred in wide-spread installations such as rolling mills, lifting gear and test rigs with a remote control cabinet. The external pilot oil return allows a shared tank line with other consumers. The pilot stage itself is fed internally from port P.
