Extrusion is not about switching speed, it is about a feed rate that stays the same for minutes on end. The 4WRZE32W6-520-7X holds its nominal flow of 520 l/min at 350 bar for that, guided by a low-drift 4 to 20 mA current command.
Benefits
- 4 to 20 mA current command for a feed rate that stays stable over long strokes, supply 24 VDC.
- 520 l/min nominal flow, size 32, flow up to 1600 l/min.
- External pilot supply with external drain, independent of pressure in the main circuit.
- Spool symbol W6 with three switching positions across four ports.
- 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.8 kg.
- ISO 4401-10-09-0-05 subplate mounting with a 7-pole connector (6 + PE) to EN 175201-804.
