Total price
Forging lines run hard load changes, during which the pilot circuit has to stay independent. The 4WRTE27E500L-4X/6EG24K31/F1M therefore takes pilot oil from outside and drains it outside. The command value arrives as a current of 4 to 20 mA, and 500 l/min nominal flow is metered.
Benefits
- Spool symbol E with 3 switching positions suits motion profiles with a defined centre position.
- A 4 to 20 mA current command works reliably in electrically noisy surroundings.
- Fully external pilot routing decouples control from pressure shocks in the working circuit.
- Nominal flow 500 l/min with a maximum of 1000 l/min at 270 bar operating pressure.
- On-board electronics, connection diagram ISO 4401-08-07-0-05, 4 ports, 19.5 kg.
- NBR seals for HL hydraulic fluid, supply 24 V DC.

Applications
The valve drives forging cylinders, ejectors and manipulator axes with a high volume demand. With pilot supply and return outside, control stays steady even during pressure shocks in the main circuit. The current command matches control systems that drive their axes from current outputs.
