Proportional Directional Valve 4WRTE25E220L-4X/6EG24ETK31/A1V - Bosch Rexroth R900738494

Some plants offer neither a stable pump pressure nor a calm return line. The 4WRTE25E220L-4X/6EG24ETK31/A1V therefore draws pilot oil from its own source and drains it separately, at 220 l/min nominal flow and 350 bar operating pressure.

Benefits

• Pilot oil supply and drain are routed externally, so the pilot stage works independently of the main circuit.
• 220 l/min nominal flow and up to 870 l/min maximum flow.
• A ±10 V command value at the on-board electronics, 24 VDC supply.
• Spool symbol E, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
• 350 bar operating pressure, FKM seals, 18 kg valve mass.

Application

A fit for linked plants with accumulator operation and strongly changing load, for example in forming technology. Two additional pilot oil lines have to be planned. The voltage command suits installations where the control card sits close to the valve.

Manufacturer

Bosch Rexroth lists this valve under material number R900738494. Electrical connection is a 7-pole connector (6 + PE) to EN 175201-804.
