Proportional Directional Valve 4WRZE32E520-7X/6EG24N9K31/F1M - Bosch Rexroth R901204397

A test cycle that deliberately lets system pressure collapse must not drag the pilot stage along. The 4WRZE32E520-7X/6EG24N9K31/F1M draws pilot oil externally and drains it externally while metering 520 l/min at 350 bar from a 4...20 mA current command.

Benefits

• External pilot oil supply and external drain through X and Y, independent of test pressure.
• 520 l/min nominal flow at 350 bar, the body limit stands at 1600 l/min.
• E spool, three switching positions, four ports, ISO 4401-10-09-0-05 interface.
• 4...20 mA current command, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804.
• 44 kg installed weight, NBR seals, HL hydraulic fluid, UKCA for electromagnetic compatibility.

Applications

The valve suits material and component test rigs, hydraulic pulse facilities and forming presses with a dedicated control pressure circuit. An external pilot circuit allows testing at very low working pressure. The concealed auxiliary actuation remains reachable in a fault case.
