Proportional Directional Valve 4WRTE25W6-350L-4X/6EG24EK31/F1M - Bosch Rexroth R901127122

A current command brings diagnosis along with it, since a cut cable results in 0 mA instead of an apparently valid value. The 4WRTE25W6-350L-4X/6EG24EK31/F1M is steered that way and meters 350 l/min nominal flow at an operating pressure of up to 350 bar.

Benefits

• Command value 4 to 20 mA, a broken wire shows up as loss of current
• 350 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
• Internal pilot oil supply with external return, operating pressure up to 350 bar
• Spool symbol W6 with three switching positions across four ports, internal spool position feedback
• 17.92 kg weight, NBR seals for HL hydraulic fluid, connection diagram ISO 4401-08-08-0-05

Applications

The valve is intended for presses, test rigs and conveying equipment where the axis has to stop in a defined way on fault. Internal pilot supply assumes a P port that carries pressure permanently. Supply through a connector, 7-pole (6 + PE) according to EN 175201-804 at 24 V DC.
