Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9K31/F1V - Bosch Rexroth R901011154

In deep drawing the required blank holder force travels with the draw, otherwise the sheet tears or wrinkles. The 4WRZE10W8-85-7X/6EG24N9K31/F1V follows the command curve at 85 l/min rated flow and 315 bar maximum, taking the signal as a 4...20 mA current.

Benefits

• Force curve over the draw travel set through the 4...20 mA current command value.
• 85 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Spool symbol W8 with three switching positions and a blocked centre.
• External pilot oil supply and external pilot oil return, without a pressure reducing valve.
• Concealed manual override, 8.72 kg, size 10, FKM seals, HL fluid.

Application

Draw cushions, ejectors and blank holders on forming presses are the usual mounting place. External pilot supply keeps the pilot stage working even when the main circuit is unloaded. Where a voltage signal is specified, the series carries the A1 code.
