Proportional Directional Valve 4WRTE10E1-50L-4X/6EG24K31/F1M - Bosch Rexroth R901102750

Where an accumulator lets system pressure drift between charging and discharging, the pilot stage should stay unaffected. The 4WRTE10E1-50L-4X/6EG24K31/F1M uses external pilot oil supply and external return at a 50 l/min nominal flow.

Advantages

• External pilot circuit, so pilot pressure does not follow the swings at port P.
• Nominal flow of 50 l/min, operating pressure up to 350 bar.
• Current command 4...20 mA, suitable for cable runs reaching distant control cabinets.
• Spool symbol E1, four ports, connection diagram ISO 4401-05-05-0-05.
• Internal spool position feedback keeps the characteristic repeatable over the whole travel.
• Weight of 9.84 kg, NBR seals, on-board electronics running on 24 VDC.

Applications

The layout fits clamping systems, accumulator circuits and plants with cyclic pressure drops. A separate pilot circuit allows pilot pressure to be set to a fixed level. Manifold design has to include the additional X and Y ports.
