Proportional Directional Valve 4WRTE27V1-500L-4X/6EG24ETK31/A1M - Bosch Rexroth R901356557

The fewer lines a manifold needs, the less can leak. The 4WRTE27V1-500L-4X/6EG24ETK31/A1M therefore does without separate pilot lines, supplies itself internally and drains internally, at 500 l/min nominal flow and up to 270 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no additional fittings.
• 500 l/min nominal flow, maximum flow 1000 l/min, size 27.
• ±10 V command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol V1, 3 switching positions, spool position feedback in the electronics.
• NBR seals, ISO 4401-08-07-0-05 interface, 19.4 kg.

Applications

This version suits compact power units without a dedicated pilot pump, for instance on machine tools and smaller presses. It requires a system pressure that reliably reaches the minimum pilot pressure. Up to 270 bar the control stays inside the specified range.
