Description

High flow rate and a loaded return line do not exclude each other once the pilot stage drains separately. In version EK the 4WRKE25E1-350L-3X takes pilot oil internally and leads it out through Y, which leaves 350 l/min nominal flow and 350 bar operating pressure available. Control is by ±10 V.

Benefits

Internal pilot oil supply, external pilot oil return through Y
350 l/min nominal flow, flow rate up to 870 l/min
±10 V command value, 24 V DC supply, on-board electronics
Operating pressure up to 350 bar, spool symbol E1
17.8 kg weight, ISO 4401-08-08-0-05 connection diagram

Applications

A typical installation is in presses and lifting gear whose return runs through coolers and filters. The dedicated Y port keeps the pilot drain clear of them. Electrically the valve connects through the 7-pole connector (6 + PE) to EN 175201-804.

Manufacturer
