Proportional Directional Valve 4WRTE16V1-220L-4X/6EG24ETK31/F1M - Bosch Rexroth R901404220

On the clamping unit of a plastics machine every saved pipe run counts. The 4WRTE16V1-220L-4X/6EG24ETK31/F1M takes pilot oil internally and returns it internally while metering 220 l/min nominal flow at up to 350 bar.

Benefits

• Internal pilot supply and internal return save two pipe runs per valve station.
• 220 l/min nominal flow in size 16, series maximum flow 460 l/min.
• Spool symbol V1 with 3 switching positions, mounting pattern ISO 4401-07-07-0-05.
• 4...20 mA command over a 7-pole connector (6 + PE) to EN 175201-804, 24 VDC supply.
• Low weight of 11 kg within the size, NBR seals for HL fluid.

Applications

The valve is used on clamping and injection units, on core pull axes and in blow moulding lines. The internal pilot path shortens assembly time and reduces the number of fittings. The current interface stays interference proof next to heater bands and drives.
