Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9K31/A1V - Bosch Rexroth R900958872

Where the pilot supply already exists in the plant, the main valve can route both pilot paths outside and concentrate on the main flow. The 4WRZE32E1-520-7X/6EG24N9K31/A1V does so with spool symbol E1, 520 l/min nominal flow and 350 bar operating pressure.

Benefits

• Spool symbol E1 with three switching positions across four ports, ISO 4401-10-09-0-05 mounting pattern.
• 520 l/min nominal flow, up to 1600 l/min maximum, 350 bar operating pressure.
• External pilot oil supply and external pilot oil return, matched to a central pilot station.
• ±10 V command value into the on-board electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals for HL hydraulic fluid, concealed manual override, weight 43.1 kg.

Applications

The valve drives main axes in presses, forging plant and hydraulic test rigs served by a central pilot supply. The bipolar ±10 V command lets the machine controller set direction and opening in a single signal.
