Proportional Directional Valve 4WRKE25R350L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901125163

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

Technical data

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.
