Description

Large axes often sit far away from the control cabinet. This size 25 valve therefore accepts a 4...20 mA current command value and converts it into 350 l/min nominal flow at operating pressures up to 350 bar.

Advantages

Command value 4...20 mA for interference-free transmission over long cables
Nominal flow 350 l/min, maximum flow up to 870 l/min
External pilot oil return with internal supply
Symbol W6, three switching positions, four ports to ISO 4401-08-08-0-05
Linear characteristic curve with fine control range, on-board electronics on 24 VDC
Operating pressure up to 350 bar, 17.9 kg, NBR seals for HL hydraulic fluid

Applications

Used on widely distributed hydraulic axes such as rolling mills and lock gate drives. The separate return keeps pilot control stable even when port T is pressurised. The 7-pole connector to EN 175201-804 carries command value and supply together.

Manufacturer

Bosch Rexroth, material number R901066669. The full type designation is 4WRKE25W6-350P-3X/6EG24EK31/F1D3M.
