Proportional Directional Valve 4WRTE10W8-100L-4X/6EG24K31/A1M - Bosch Rexroth R900954262

On test rigs a pressure collapse is part of the programme and the valve control must not follow it. The 4WRTE10W8-100L-4X/6EG24K31/A1M is therefore piloted externally and meters a 100 l/min nominal flow on a plus/minus 10 V command.

Advantages

• External pilot oil supply and external return, independent of how main pressure behaves.
• Nominal flow of 100 l/min, up to 170 l/min at pressures reaching 350 bar.
• Plus/minus 10 V command matching test rig controllers with analogue outputs.
• Spool symbol W8, three switching positions, four ports.
• Internal spool position feedback preserves the relation between command and opening.
• Weight of 8.44 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications

Material and component test rigs as well as simulation systems are the typical duties. A separate pilot circuit makes it possible to run load profiles down to pressure collapse without losing valve dynamics. Interface and hole pattern follow ISO 4401-05-05-0-05.
