Proportional Directional Valve 4WRTEM25E1-220L-4X/6EG24EK31/F1M - Bosch Rexroth R901507405

The valve accepts its command as a 4...20 mA current, converting it to up to 220 l/min through spool symbol E1, at 350 bar operating pressure with an 870 l/min flow limit. Pilot oil is tapped internally, the drain is led outside.

Benefits

• Current command 4...20 mA, noise resistant across wide distances in a plant
• 220 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
• Internal pilot supply with external drain, insensitive to return pressure
• Spool symbol E1, 3 switching positions across 4 ports
• NBR seals for HL fluid, mass of 17.5 kg

Applications

The combination is used in sprawling production plants where the controller does not stand next to the machine while the tank return builds pressure. Internal pilot pickup saves a line. Installation is on a subplate to ISO 4401-08-08-0-05.
