Proportional Directional Valve 4WRTE16W8-150L-4X/6EG24ETK31/A1M - Bosch Rexroth R901496406

A power unit without a second pump is cheaper, quieter and needs less maintenance. The 4WRTE16W8-150L-4X/6EG24ETK31/A1M does without a pilot pump because it takes pilot oil internally and returns it internally, metering 150 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no separate pilot pump required.
• 150 l/min nominal flow, maximum flow 460 l/min in size 16.
• Spool symbol W8 with a linear characteristic curve, 3 switching positions and 4 ports.
• ±10 V command value on the on-board electronics, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.
• Operating pressure up to 350 bar, connection diagram ISO 4401-07-07-0-05, 11.3 kg weight.

Technical data

Applications

The valve suits stand alone power units on presses, bending machines and test rigs where system pressure stays high throughout. Doing without a pilot pump removes a drive, a filter and one more maintenance point. At 150 l/min the axis remains brisk on both working and return stroke.
