Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R901154222

Two boundary conditions shape this variant. The command value is a ±10 V voltage signal, and the pilot oil return runs separately to tank while the supply stays internal. That keeps the 360 l/min nominal flow of this size 32 valve accurate even when the return line is under pressure. Operating pressure reaches 350 bar, weight is 37 kg.

Key benefits

• Internal supply with external pilot oil return, insensitive to back pressure at the tank port
• ±10 V command value straight from the analog card, direction from the sign
• 360 l/min nominal flow with a 1600 l/min ceiling
• 350 bar operating pressure, connection diagram ISO 4401-10-09-0-05
• 37 kg weight in size 32
• Spool symbol W6, 4 ports, 3 switching positions, FKM seals for HL hydraulic fluid

Applications

The layout suits circuits with a return filter or an oil cooler where the tank port is not pressure free. Control comes from existing analog peripherals without a signal converter. Typical machines are presses, test benches and forming equipment with cylinders around 360 l/min.
