Description

Long return lines to tank build up back pressure that disturbs the pilot stage. The 4WRKE25R350L-3X/6EG24EK31/A1D3M therefore drains pilot oil separately to the outside, takes it internally and meters 350 l/min nominal flow at up to 350 bar.

Benefits

External pilot oil return for a defined back pressure at the pilot stage
Internal pilot supply, no additional feed port needed on the manifold
350 l/min nominal flow, spool symbol R with a linear characteristic
±10 V command on the on-board electronics, weight 17.88 kg

Applications

Suited to widely spread installations with a central tank, for example rolling mills or paper machines. Internal spool position feedback secures repeat accuracy even when return pressure varies. Hydraulic fluid HL, NBR seals.

Manufacturer

Bosch Rexroth, material number R901125163. The type code 4WRKE25R350L-3X/6EG24EK31/A1D3M defines size, spool symbol, electronics and seal material without ambiguity.
