Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9K31/A1V - Bosch Rexroth R901136640

A hold-down that gives way during the cut produces burr and dimensional error. The 4WRZE10W8-85-7X/6EG24N9K31/A1V keeps it blocked through spool symbol W8 at centre and supplies 85 l/min rated flow at 315 bar maximum while travelling.

Benefits

• Spool symbol W8 blocks at centre and holds the hold-down in place without actuation.
• 85 l/min rated flow for short idle times, flow up to 170 l/min.
• External pilot oil supply and external pilot oil return, without a pressure reducing valve.
• Operating limit 315 bar, size 10, port pattern ISO 4401-05-05-0-05, 8.02 kg.
• Command value 10 V bipolar, 24 VDC supply, concealed manual override, FKM seals for HL fluid.

Application

Punching and nibbling machines, press brakes and trimming stations use the valve on hold-down and infeed axes. The concealed manual override allows a jammed tool to be lifted without control voltage. For smaller cylinders, 25 and 50 l/min are available.
