Proportional Directional Valve 4WRKE16E150L-3X/6EG24K31/A1D3M - Bosch Rexroth R901527927

A forging manipulator reverses load and direction at short intervals, which puts demands on the pilot stage of a valve. On the 4WRKE16E150L-3X/6EG24K31/A1D3M pilot supply and pilot drain are therefore external, keeping pilot pressure independent of the main circuit, at 150 l/min nominal flow and 350 bar operating pressure.

Benefits

• External pilot path on both sides, pilot pressure stays steady through load changes
• 150 l/min nominal flow, headroom up to 460 l/min maximum flow
• 350 bar operating pressure in size 16 on the ISO 4401-07-07-0-05 pattern
• Internal position feedback with on-board electronics, ±10 V command value at 24 VDC
• Spool symbol E, NBR seals, 11.8 kg, HL hydraulic fluid

Applications

The valve serves manipulators, forging presses and hammer drives with frequent reversals. A separate pilot circuit stops pressure dips in the main channel from reaching control quality. The NBR seals are matched to HL hydraulic fluid.
