This variant draws its pilot oil from outside through X but returns it internally into the tank line. The pilot level therefore stays constant without a second line to the reservoir. Nominal flow is 500 l/min at 270 bar.

Description

The 4WRKE27W8-500L-3X/6EG24TK31/A1D3M is the mixed form of the 500 l/min series. External supply through X secures the pilot level even when the system collapses during the cycle, while the internal return saves one line. Spool symbol W8 works linearly and the command arrives as a ±10 V voltage.

Benefits

External pilot supply through X with internal return, one line fewer at the block.
Pilot level stays independent of the main circuit.
Spool symbol W8 with a linear curve, 500 l/min nominal flow, up to 1000 l/min.
±10 V command, operating pressure to 270 bar, 24 VDC supply.
NBR seals, 19.35 kg, mounting pattern ISO 4401-08-08-0-05.

Application

The valve suits presses and test rigs whose system level swings widely during the cycle and which still need repeatable switching times. Mineral oil of class HL is the intended fluid. It is wired through a 7-pole plug to EN 175201-804.
