Proportional Directional Valve 4WRTE16E1-220L-4X/6EG24K31/A1M - Bosch Rexroth R901548102

An axis reversing every second keeps the pilot circuit busy without pause, stroke after stroke. The 4WRTE16E1-220L-4X/6EG24K31/A1M therefore draws pilot oil from a dedicated circuit, drains back into it and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• External pilot oil supply and external pilot oil return, steady pilot pressure at high cycle rates.
• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• Spool symbol E1 with a linear characteristic curve, 3 switching positions and 4 ports.
• ±10 V command value, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.
• Operating pressure up to 350 bar, connection diagram ISO 4401-07-07-0-05, 11.04 kg weight.

Applications

The valve works on punching machines, forging hammers and indexing presses with short cycle times. A dedicated pilot circuit supplies the same pilot pressure on every stroke, whatever the working circuit happens to be doing. At 220 l/min the axis stays fast enough even at high stroke rates.
