Proportional Directional Valve 4WRZE32E1-360-7X/6EG24EK31/A1D3M - Bosch Rexroth R900727933

Replacing a pilot-operated valve depends not only on frame size and symbol but also on which pilot ports the manifold provides. The 4WRZE32E1-360-7X/6EG24EK31/A1D3M takes pilot oil internally yet requires an external drain over port Y, working at 360 l/min nominal flow and 350 bar.

Key benefits

• Internal supply with external drain - a clearly defined combination that should be checked on the manifold before a swap.
• Pilot return led to tank without pressure - main circuit return pressure does not act on the pilot stage.
• 360 l/min nominal flow, up to 1600 l/min by valve size - operating pressure up to 350 bar.
• Spool symbol E1 on ISO 4401-10-09-0-05 - 4 ports, 3 switching positions, subplate mounting.
• Command value ±10 V, supply 24 VDC - on-board electronics on a 7-pole connector (6 + PE) to EN 175201-804.
• 43.8 kg, NBR seals - laid out for hydraulic fluid HL, EMC to UKCA SI2016/1091.

Applications

The valve is used in presses, hoists and test rigs with heavily loaded returns, where tank pressure would disturb the pilot stage through the internal path. Before installation, check that the manifold carries port Y and that it leads to tank without pressure. The valve is pilot-operated and built as a spool valve.
