Proportional Directional Valve 4WRDE25V350L-6X/MPT/24A5 - Bosch Rexroth R901569729

Cutting the stroke time of a size 25 axis needs more nominal flow without changing the subplate. The 4WRDE25V350L-6X/MPT/24A5 supplies 350 l/min at 350 bar and still feeds spool position back internally.

Benefits

• 350 l/min nominal flow for shorter stroke times than the 220 l/min build.
• ISO 4401-08-08-0-05 interface unchanged, so a swap within the series needs no manifold work.
• Internal spool position feedback keeps control quality at the higher throughput.
• Pilot oil supplied and drained internally, operating pressure up to 350 bar, flow up to 870 l/min.
• 17.5 kg weight, symbol V, three switching positions, four ports.

Application

The larger nominal flow pays off on rapid traverse motion, fast return strokes and large cylinder areas. Because command range and electronics stay the same, only the scaling changes in the controller. Internal pilot routing keeps piping work low.
