Proportional Directional Valve 4WRZE10E85-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900943818

This proportional directional valve controls a size 10 actuator steplessly at 85 l/min nominal flow. Because pilot supply and pilot return are internal, only the four main ports have to be piped, and the 4...20 mA current command keeps the control insensitive to pickup.

Benefits

• The combination of internal pilot stage and 4...20 mA current command saves pipework and screens out interference voltage
• 85 l/min nominal flow with a maximum flow of 170 l/min
• 315 bar operating pressure, 3 switching positions, spool symbol E, 4 ports
• On-board electronics, 24 VDC, no amplifier card needed in the cabinet
• FKM seals for HL hydraulic fluid, UKCA to SI2016/1091 with EMC evidence

Applications

The valve pays off wherever power units are built tightly and loaded electrically, for example in press lines with many inverters. Internal pilot supply requires a sufficiently high system pressure. Weight is 8.45 kg.
