Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901114460

A replacement is decided first by the spool symbol, because it has to match the hydraulic diagram: this version carries symbol E1 and works at 520 l/min nominal flow on a ±10 V command value.

Key benefits

• Symbol E1 in 3 switching positions over 4 ports on the ISO 4401-10-09-0-05 interface.
• 520 l/min nominal flow in a body rated for flows up to 1600 l/min.
• ±10 V command value on a 24 VDC supply, the electronics are built into the valve.
• Both pilot oil paths external, the integrated pressure reducing valve keeps pilot pressure constant up to 350 bar operating pressure.
• 44.2 kg mass, NBR seals for HL hydraulic fluid.

Applications

Press hydraulics, large injection moulding machines and hoisting gear are the main field, wherever an existing valve station is refitted. Because the interface is standardised, the subplate usually stays as it is. Electrical hookup uses a 7-pole connector (6 + PE) to EN 175201-804.
