Proportional Directional Valve 4WRDE16V1N220L-6X/MXY/24F1 - Bosch Rexroth R901579108

Between 125 and 250 l/min it becomes a question of whether size 16 still suffices for an axis. This pilot-operated proportional directional valve exhausts the frame size at 220 l/min of nominal flow, permits peaks to 460 l/min plus holds 350 bar of operating pressure, driven by an impressed 4-20 mA command value.

Benefits

• Nominal flow of 220 l/min in size 16 allows a more compact manifold layout than NG25
• Maximum flow of 460 l/min gives reserve for rapid traverse phases
• Spool symbol V1 with linear characteristic curve backed by internal spool position feedback
• A 4-20 mA current command value resists interference, wire break shows as 0 mA
• Operating pressure to 350 bar, connection diagram ISO 4401-07-07-0-05, mass 9.95 kg

Application

A fit for approach plus feed axes on forming machines, test rigs along with handling equipment. Where an NG25 valve used to sit, size 16 saves installation space as well as mass on the manifold. External pilot oil routing allows a dedicated pilot pressure level.
