Proportional Directional Valve 4WRZE32E520-7X/6EG24N9K31/A1M - Bosch Rexroth R900247388

Changing loads pull the speed of a simple valve away as soon as load pressure rises. The 4WRZE32E520-7X/6EG24N9K31/A1M holds the command value through its piston position feedback and meters 520 l/min at 350 bar from a ±10 V command.

Benefits

• Piston position feedback inside the valve holds the relation between command and flow under changing load pressure.
• 520 l/min at 350 bar in size 32, body limit 1600 l/min.
• External pilot oil supply and external drain keep the axis independent of pressure in the main circuit.
• E spool, four ports, three switching positions, ISO 4401-10-09-0-05 interface.
• 43.48 kg, ±10 V command on 24 V DC, NBR seals, HL hydraulic fluid.

Applications

The valve suits deck cranes, ramps, hatch covers and heavy lifting axes ashore. External pilot supply makes the axis independent of pressure in the main circuit. At 350 bar and 520 l/min even large cylinders keep moving briskly.
