Description

Return line pressure and the current interface define this ordering variant. In the 4WRKE25W8-220L-3X in version EK pilot oil comes internally from the P line and leaves through the Y port to tank without pressure, while a 4...20 mA command value meters 220 l/min nominal flow. Operating pressure may reach 350 bar.

Benefits

Internal pilot oil supply, external pilot oil return through Y
4...20 mA current command value, suitable for long signal runs
220 l/min nominal flow, flow rate up to 870 l/min
Spool symbol W8, four ports, three switching positions
18.08 kg weight, operating pressure up to 350 bar

Applications

This version is used in plants with a shared return, for example presses driving several cylinders. Electronics on the valve save an amplifier card in the cabinet. Supply is 24 V DC through the 7-pole connector (6 + PE) to EN 175201-804.
