Proportional Directional Valve 4WRKE16W6-150L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901479824

The cutting stroke of a plate shear creates short pressure peaks in the tank line that can reach the pilot stage. The 4WRKE16W6-150L-3X/6EG24EK31/F1D3M keeps them away through an external pilot drain, works at 150 l/min nominal flow and accepts the command value as a 4...20 mA current.

Benefits

• External pilot drain, pressure peaks in the tank line never reach the pilot stage
• 150 l/min nominal flow at 460 l/min maximum flow
• 4...20 mA current command value at the on-board electronics, no amplifier card
• 350 bar operating pressure in size 16, weight 12.05 kg
• Spool symbol W6, NBR seals, ISO 4401-07-07-0-05 connection diagram

Applications

The valve serves shears, punching machines and sawing lines where several axes push large oil volumes into the tank line for a short moment. A dedicated pilot drain keeps the pilot working point clear of that. A 24 VDC supply is enough for control.
