Proportional Directional Valve 4WRTE27W6-500L-4X/6EG24K31/A1M - Bosch Rexroth R900977345

Grown installations often carry a dedicated pilot pump whose pipework nobody wants to change. The 4WRTE27W6-500L-4X/6EG24K31/A1M fits there, because pilot oil supply and return are both external. It meters 500 l/min nominal flow from a ±10 V voltage command.

Benefits

• External pilot oil supply and external return match the existing pipework.
• A ±10 V command value works with the installed axis controller without electrical rework.
• Nominal flow 500 l/min and maximum flow 1000 l/min in size 27.
• Spool symbol W6 keeps the centre position function of the existing circuit diagram.
• Connection diagram ISO 4401-08-07-0-05, 270 bar operating pressure, 4 ports, 19.5 kg.
• On-board electronics at 24 V DC, 7-pole connector (6 + PE) according to EN 175201-804.

Applications

The valve serves presses, lifting gear and feed axes designed around a separate control oil supply. Since connection diagram and spool symbol follow the series standard, the manifold stays untouched. The voltage command suits common analogue output cards.
