Proportional Directional Valve 4WRKE32W8-400P-3X/6EG24ETK31/F1D3V - Bosch Rexroth R901422953

Once a cylinder is filled with several hundred litres per minute, control quality decides both cycle time and end position behaviour. The 4WRKE32W8-400P is built for that with 400 l/min nominal flow, up to 1550 l/min maximum flow and 350 bar operating pressure.

Benefits

• 400 l/min nominal flow and up to 1550 l/min peak flow in size 32.
• 350 bar operating pressure with FKM seals, rated for higher fluid temperatures than NBR.
• Linear characteristic with fine control range plus internal piston position feedback for high repeat accuracy.
• 4 to 20 mA current command through the on-board electronics, unaffected by voltage drop on long signal runs.
• 50 kg weight on connection diagram ISO 4401-10-09-0-05, with internal pilot oil supply and internal return.

Technical data

Applications

The valve drives main axes on large presses, rolling mills and forging lines where short fill times and exact end positions have to coincide. The FKM version suits plants running at elevated oil temperature. HL is the specified fluid.
