Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901007261

Current signal outside, pilot oil inside: this pairing joins an interference-tolerant 4 to 20 mA command value to internal pilot pickup and yields 520 l/min nominal flow.

Key benefits

• 4 to 20 mA current command with internal pilot pickup, cutting signal work and pipework at the same time.
• External pilot oil return through a dedicated line, independent of pressure in the tank channel.
• 520 l/min nominal flow in a body released for flows up to 1600 l/min.
• Spool symbol W8, 3 switching positions, 4 ports, interface ISO 4401-10-09-0-05.
• 43.8 kg, integrated pressure reducing valve to 350 bar, NBR seals for HL hydraulic fluid.

Applications

The variant pays off in large power units with a central control room, where long signal runs meet a loaded tank line. Pilot pressure is taken from the main circuit, so no extra pump is required. Electrical hookup is a 7-pole connector (6 + PE) to EN 175201-804.
