Proportional Directional Valve 4WRTE16E220L-4X/6EG24K31/A1M - Bosch Rexroth R901430240

When pilot pressure comes from an accumulator or an auxiliary pump, the valve has to accept a dedicated X line. The 4WRTE16E220L-4X/6EG24K31/A1M is built with external pilot oil supply and return and is driven by a ±10 V voltage command.

Benefits

• External pilot oil supply and return through the X and Y lines.
• Command value ±10 V, matched to existing analog outputs.
• 220 l/min nominal flow in size 16, up to 460 l/min maximum.
• Spool symbol E with internal spool position feedback.
• 11.04 kg weight, 350 bar maximum operating pressure, NBR seals.

Applications

The valve suits plants whose main pressure can fall below the minimum pilot pressure during the cycle, for example while an accumulator discharges. The pilot stage stays supplied and the axis remains controllable. Subplate mounting to ISO 4401-07-07-0-05 is unchanged from the internally piloted variant.
