Proportional Directional Valve 4WRTE10E1-100L-4X/6EG24EK31/A1M - Bosch Rexroth R900978330

Position control loops usually output their command as a voltage and expect a repeatable valve opening. The 4WRTE10E1-100L-4X/6EG24EK31/A1M delivers a 100 l/min nominal flow for that and measures spool position internally.

Advantages

• Plus/minus 10 V command fed directly from the position controller to the on-board electronics.
• Nominal flow of 100 l/min so that larger cylinders also travel briskly.
• Internal spool position feedback keeps the relation between command and opening constant.
• Internal pilot oil supply with external return through port Y.
• Operating pressure up to 350 bar, flow up to 170 l/min, spool symbol E1.
• Weight of 8.5 kg, NBR seals, HL hydraulic fluid.

Applications

It is used on controlled positioning axes of presses, test rigs and handling gantries. The external return keeps the pilot stage independent of return pressure. Subplate mounting to ISO 4401-05-05-0-05 allows a swap on existing manifolds.
