Proportional Directional Valve 4WRZE25E325-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900955077

When back pressure in the tank line rises, pilot control is the first thing to suffer. This valve answers that with an internal pilot feed and a separate return through Y, while controlling 325 l/min with spool symbol E.

Benefits

• Separate pilot return through Y, independent of back pressure in the main tank circuit
• Internal pilot feed, so no dedicated pilot pump is needed
• 325 l/min nominal flow, spool symbol E, operating pressure up to 350 bar
• Command value ±10 V, on-board electronics, supply 24 VDC
• Mass 20.65 kg, subplate mounting ISO 4401-08-08-0-05

Application

This configuration proves itself on plants with long or heavily loaded tank lines where return pressure climbs noticeably. Large presses and test rigs with a shared return manifold belong in that group. The Y line has to run separately to tank without a filter or restrictor in the path.
