Proportional Directional Valve 4WRTE10E1-100L-4X/6EG24K31/A1M - Bosch Rexroth R900706974

During injection the system pressure rises within milliseconds and the pilot stage should stay unimpressed. The 4WRTE10E1-100L-4X/6EG24K31/A1M is therefore fed from its own pilot circuit and meters a 100 l/min nominal flow.

Advantages

• External pilot oil supply and external return for a stable operating point during pressure build-up.
• Nominal flow of 100 l/min, up to 170 l/min total, operating pressure up to 350 bar.
• Plus/minus 10 V command taken straight from the machine controller card.
• Spool symbol E1 with three switching positions on four ports.
• Internal spool position feedback for repeatable injection profiles.
• Weight of 9.42 kg, NBR seals, subplate mounting ISO 4401-05-05-0-05.

Technical data

Applications

It is used on injection, holding pressure and clamping axes of plastics machinery. The valve equally fits forming presses with rapid pressure build-up. Ports X and Y have to be provided on the manifold for the pilot stage.
