Proportional Directional Valve 4WRTE16V220L-4X/6EG24K31/A1M - Bosch Rexroth R901398534

A press with an established control system is not converted to fieldbus because of one valve. The 4WRTE16V220L-4X/6EG24K31/A1M stays with the plus or minus 10 V command and meters 220 l/min nominal flow at operating pressures up to 350 bar, with external pilot supply and external return.

Benefits

• A plus or minus 10 V command allows replacement without touching the control card or wiring.
• 220 l/min nominal flow in size 16, series up to 460 l/min.
• External pilot oil supply and external return for power units with a pilot pump.
• Spool symbol V, 3 switching positions, 4 ports to ISO 4401-07-07-0-05.
• On-board electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804, 11.26 kg.

Applications

The valve controls press rams, die cushions and ejector axes in forming technology. Because the pilot circuit is supplied separately, actuating times stay stable during pressure dips in the working circuit. The NBR seals are designed for mineral oil of class HL.
