Proportional Directional Valve 4WRTE10E1-50L-4X/6EG24K31/A1V - Bosch Rexroth R901135806

Symbol E1 is chosen when the centre position has to behave in a specific way that a replacement must not alter. The 4WRTE10E1-50L-4X/6EG24K31/A1V provides that symbol at 50 l/min nominal flow with a linear characteristic and external piloting, at up to 350 bar.

Benefits

• Size 10 with spool symbol E1, rated at 50 l/min nominal flow.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• Spool position control works with internal feedback, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• Command value input ±10 V on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• FKM seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.45 kg weight.

Applications

The valve is used on controlled axes in testing machines, plastics machinery and special installations with a central pilot circuit. The linear characteristic simplifies tuning of the superimposed controller. For replacements, symbol E1 and component series 4X are the decisive details.
