Description

Large flow rates and an independent pilot stage often belong together in presses. The 4WRKE25W8-350L-3X takes pilot oil externally and returns it externally, so the main stage stays under control at 350 l/min nominal flow regardless of load pressure. The command value arrives as ±10 V.

Benefits

External pilot oil supply and external pilot oil return
350 l/min nominal flow, flow rate up to 870 l/min
±10 V command value, 24 V DC supply, on-board electronics
Spool symbol W8, operating pressure up to 350 bar
17.92 kg weight, ISO 4401-08-08-0-05 interface

Applications

The valve is used in forming machines, lifting gear and test installations with their own pilot pump. The separate circuit allows dedicated filtering for the pilot stage. HL hydraulic fluid is approved.

Manufacturer
