Description

When system pressure drops for part of the cycle, the pilot stage needs a source of its own. In version TK the 4WRKE25W8-220L-3X receives pilot oil through the X port and returns it internally, so 220 l/min nominal flow can still be metered cleanly. The command value is applied as ±10 V.

Benefits

External pilot oil supply through X, internal pilot oil return
Pilot stage keeps working when pressure in the P line collapses
220 l/min nominal flow, flow rate up to 870 l/min
±10 V command value, on-board electronics, 24 V DC supply
18.04 kg weight, operating pressure up to 350 bar

Applications

Circuits like this appear on presses with an unloading phase and on accumulator driven systems. Spool symbol W8 connects the ports in the centre position as shown in the hydraulic symbol. Mounting is on size 25 subplates.
