Changing a screen on a running extruder must not let melt conditions jump. The 4WRZE10W6-50-7X/6EG24ETK31/F1D3V drives the cylinder at 50 l/min rated flow and 315 bar maximum, and spool symbol W6 gives the overlap suited to axes that have to block in centre position.
Benefits
- Spool symbol W6 with three switching positions for axes that should block at centre.
- 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
- Internal pilot oil supply and internal pilot oil return, plus a pressure reducing valve in the pilot stage.
- Current command value 4...20 mA into the on-board electronics, 24 VDC supply.
- Size 10, port pattern ISO 4401-05-05-0-05, 9.16 kg, FKM seals for HL fluid.
