Total price
Existing plants usually dictate the pilot circuit and the signal type, so a replacement valve has to fit in. The 4WRTE27W8-500L-4X/6EG24K31/F1M does that with external pilot oil supply, external return, symbol W8 and 500 l/min nominal flow.
Benefits
- External pilot oil supply and external return, as commonly found in grown installations.
- Symbol W8 with three switching positions and internal spool position feedback.
- 500 l/min nominal flow, 1000 l/min maximum, operating pressure up to 270 bar.
- Current command value 4 to 20 mA, supply 24 V DC, 7-pole connector (6 + PE).
- Weight 19.46 kg, HL hydraulic fluid, mounting pattern ISO 4401-08-07-0-05.
