Proportional Directional Valve 4WRZE32W9-360-7X/6EG24N9K31/A1D3V - Bosch Rexroth R900709847

On presses and power units with their own pilot circuit, the main flow is metered by a pilot-operated directional valve. This size 32 4WRZE controls 360 l/min nominal flow, admits up to 1600 l/min and works at a maximum operating pressure of 350 bar.

Benefits

• 360 l/min nominal flow at a valve weight of 42 kg.
• Maximum flow 1600 l/min, maximum operating pressure 350 bar.
• External pilot oil supply and external pilot oil return keep the pilot stage apart from the main circuit, the built-in pressure reducing valve feeds it.
• Spool symbol W9 with 3 switching positions across 4 ports, mounting pattern ISO 4401-10-09-0-05.
• On-board electronics with ±10 V command value and 24 VDC supply, 7-pole connector (6 + PE) according to EN 175201-804.
• FKM seals for HL hydraulic fluid, concealed auxiliary actuation, UKCA conformity under SI2016/1091.

Technical data

Applications

Intended for presses, large cylinders and hydraulic power units that already carry a separate pilot circuit. The valve is pilot-operated and needs pilot oil supplied and returned externally. Its ISO 4401-10-09-0-05 pattern lets it sit on manifolds machined to that footprint. The FKM seals match HL hydraulic fluid.
