If system pressure drops during part of the cycle, the pilot stage still has to work. This 4WRTE27 draws its pilot oil externally, converts 500 l/min nominal flow and is rated for 270 bar operating pressure.

Total price
In cycles with a pressure collapse, for instance right after a tool opens, an internal pilot stage loses its force. The 4WRTE27W6-500L-4X/6EG24K31/A1V therefore uses external pilot oil supply and return while metering 500 l/min nominal flow.
Benefits
- External pilot supply - the pilot stage stays independent of any collapse in system pressure.
- 500 l/min nominal flow, up to 1000 l/min at the limit, at 270 bar.
- Symbol W6 with position feedback, ±10 V command, three switching positions.
- On-board electronics on 24 VDC, 7-pole connector (6 + PE) to EN 175201-804.
- 19.56 kg for subplate mounting to ISO 4401-08-07-0-05, FKM seals.

Application
Valves like this sit in injection moulding machines, sheet metal presses and lifting plants where pressure swings widely between phases. A dedicated pilot circuit of around 30 bar keeps response time and characteristic stable. The fluid is HL.
