Proportional Directional Valve 4WRZE32E520-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901137084

Where several axes share one valve stand, pressure in the common tank line changes with every stroke of the neighbouring axis. The 4WRZE32E520-7X takes its pilot circuit out of that influence through external supply as well as external drain, delivering 520 l/min nominal flow at 350 bar.

Benefits

• Spool symbol E with three switching positions across four ports.
• 520 l/min nominal flow in size 32, the body rated up to 1600 l/min.
• External pilot supply plus external pilot drain, with a pressure reducing valve in the pilot circuit.
• 4 to 20 mA current command at 24 VDC into the on-board electronics.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.82 kg.
• ISO 4401-10-09-0-05 subplate mounting with a 7-pole connector (6 + PE) to EN 175201-804.

Application

Forging presses or stretching mills run several large axes off one manifold, so their return strokes overlap in time. Fully external piloting keeps the valve curve stable under that condition. During maintenance the spool can be moved by hand through the concealed auxiliary actuation.
