Proportional Directional Valve 4WRDE16V220L-6X/MXY/24F1 - Bosch Rexroth R901540339

A current interface pays off in electrically noisy surroundings, and a dedicated pilot circuit in hydraulically noisy ones. The 4WRDE16V220L-6X/MXY/24F1 offers both at 220 l/min nominal flow and 350 bar.

Benefits

• 4 ... 20 mA command stays stable with long cables and heavy drives nearby.
• External pilot oil supply and external return make pilot control independent of working and tank pressure.
• 220 l/min nominal flow, maximum flow 460 l/min, operating pressure 350 bar.
• Spool symbol V with a linear characteristic, size 16, mounting pattern ISO 4401-07-07-0-05.
• 10.5 kg valve mass, NBR seals, 24 VDC supply through a 7-pole connector (6 + PE).

Applications

Suited to rolling mills, foundries and plants with many frequency converters, where analog signals are easily disturbed. A dedicated pilot circuit keeps switching times repeatable even when the main circuit is loaded in cycles. Both pilot lines have to be present at the subplate.
