A position control loop with a voltage command needs a valve that opens quickly and still tracks cleanly. The 4WRTE10E1-100L-4X/6EG24EK31/A1M releases a 100 l/min nominal flow and follows a plus/minus 10 V command.

Total price
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.
