Proportional Directional Valve 4WRTE16V1-220L-4X/6EG24K31/F1M - Bosch Rexroth R901498543

Where a separate pilot circuit already exists, the valve should use it instead of tapping the working channel. The 4WRTE16V1-220L-4X/6EG24K31/F1M therefore takes pilot oil from outside and relieves it to the outside, at 220 l/min nominal flow and up to 350 bar.

Benefits

• External pilot supply and external return keep pilot pressure independent of working pressure.
• 220 l/min nominal flow in size 16, series flow up to 460 l/min.
• Spool symbol V1 with 3 switching positions and 4 ports to ISO 4401-07-07-0-05.
• 4...20 mA command, powered with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals for HL fluid, weight 11 kg.

Applications

The valve sits in injection moulding machines, test rigs and press power units that bring their own pilot pump. Because the pilot circuit stays separate, switching behaviour hardly changes when working pressure fluctuates. The current interface avoids interference on long signal runs.
