Description

A replacement valve has to match the existing piping and the installed control card, otherwise the swap becomes expensive. The 4WRTE27W8-500L-4X/6EG24K31/A1M brings symbol W8, external piloting with external return and a ±10 V DC command value together at 500 l/min nominal flow.

Benefits

Symbol W8 in three switching positions, a widely used version for controlled cylinder axes.
External pilot oil supply and external return for plants with their own pilot circuit.
500 l/min nominal flow, 1000 l/min maximum flow, operating pressure up to 270 bar.
Command value ±10 V DC through a 7-pole connector (6 + PE), supply 24 V DC.
Weight 19.66 kg, NBR seals, HL hydraulic fluid.

Applications

The valve is fitted to presses, lifting gear and forming machines whose axes run on analogue control cards. Since connection diagram and signal type match the common version, the swap is limited to seals and bolts. An external pilot circuit has to be in place.
