Large cylinders on forging presses plus sheet forming lines demand flow without losing control quality. The 4WRDE27V500L-6X/MXT/24A1 in size 27 passes 500 l/min nominal flow, allows 1000 l/min at peak, plus draws pilot oil from an external circuit while draining internally.
Key benefits
- Nominal flow of 500 l/min alongside a peak value of 1000 l/min serves fast large bore cylinders.
- External pilot oil supply with internal return keeps the pilot stage quick even when main pressure dips.
- Operating pressure up to 270 bar with internal piston position feedback for stable holding.
- On-board electronics on a plus or minus 10 V command value, no amplifier card in the cabinet.
- Interface ISO 4401-08-08-0-05, mass of 19.5 kg, NBR seals for HL mineral oil.
