Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901043055

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.

Application

Extrusion presses, stretching lines or cold forming presses move slowly under heavy load. External piloting supplies constant control pressure even while the main circuit works at maximum pressure. Concealed auxiliary actuation stays available for maintenance as well as faults.
