Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9TK31/A1M - Bosch Rexroth R901179367

Repeatable switching times depend on a steady pilot pressure. This size 32 variant is fed externally and drains its pilot oil internally, so one return line disappears, at 520 l/min nominal flow and up to 350 bar.

Key benefits

• External pilot oil supply from a dedicated circuit, internal pilot oil return through the tank port
• Even pilot behaviour even when working pressure drops well below 350 bar
• 520 l/min nominal flow, with the size 32 body limit at 1600 l/min
• Command value ±10 V, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804
• Spool symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-10-09-0-05, 44 kg

Applications

Intended for plants with their own pilot pressure unit, such as rolling mills and forging presses with strongly varying working pressure. The internal drain assumes a tank port with low back pressure. The external pilot circuit has to be live before the main drive starts.
