Proportional Directional Valve 4WRTE16V220L-4X/6EG24K31/F1M - Bosch Rexroth R901497817

When a rolling stand is rebuilt, the power unit and its pilot pump usually stay untouched. The 4WRTE16V220L-4X/6EG24K31/F1M fits exactly there: external pilot oil supply, external return, 220 l/min nominal flow and a 4...20 mA command at operating pressures up to 350 bar.

Benefits

• 220 l/min nominal flow at 350 bar, the series reaches 460 l/min.
• External pilot with external return suits power units that have their own pilot pump.
• Spool symbol V and 3 switching positions preserve the mid position of the existing schematic.
• 4...20 mA command over a 7-pole connector (6 + PE) to EN 175201-804, 24 VDC supply.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, 11.26 kg.

Applications

The valve is used on rolling stands, strip guides and lifting axes in plant engineering. The separate pilot circuit keeps actuating times constant even when working pressure drops during the cycle. The current interface stays reliable around frequency converters and welding equipment.
