Proportional Directional Valve 4WRZE16W8-180-7X/6EG24N9K31/A1V - Bosch Rexroth R901405967

Size 16 closes the gap between sizes 10 and 25. The 4WRZE16W8-180-7X meters 180 l/min nominal flow, passes 460 l/min at peak and runs on a separately supplied pilot circuit.

Benefits

• Nominal flow of 180 l/min, maximum flow 460 l/min in size 16.
• External pilot supply and external drain, independent of the pressure profile in the main circuit.
• Build without a pressure reducing valve in the pilot stage.
• Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
• FKM seals and spool symbol W8, mass 11.74 kg.
• Maximum operating pressure 350 bar, connection diagram ISO 4401-07-07-0-05.

Application

The valve serves medium duty feed and press force axes as well as test rigs with varying system pressure. Because pilot pressure is fed in from outside, switching behaviour survives a drop of main pressure. Ports X and Y have to be provided in the manifold.
