Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901033132

Once a separate pilot pump sits in the power unit, external piloting pays off. This size 25 valve takes pilot oil from outside, drains it internally to tank and meters 325 l/min nominal flow at up to 350 bar.

Benefits

• 325 l/min nominal flow with a permissible flow of up to 870 l/min.
• Maximum operating pressure 350 bar, spool symbol W9 with three switching positions across four ports.
• Integrated pressure reducing valve keeps the pilot pressure steady.
• Concealed manual override for commissioning and fault finding without electrical power.
• On-board electronics with a ±10 V command value at 24 VDC supply voltage.
• NBR seals, HL hydraulic fluid, installed weight 21.12 kg, UKCA conformity.

Applications

The valve suits presses, forging lines and test rigs where a central pilot supply feeds several axes. The internal pilot return saves a separate line back to tank. A ±10 V command value moves the spool steadily, which keeps acceleration and braking ramps smooth.
