Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R900747095

Where a controller output already delivers plus minus 10 V, the voltage version saves the signal converter. The 4WRZE25E1-325-7X/6EG24N9EK31/A1D3M accepts that command value straight at its on-board electronics, setting up to 325 l/min rated flow at 350 bar.

Benefits

• Command value plus minus 10 V straight from the analogue output, no extra converter between control system and valve.
• 325 l/min rated flow at 350 bar, maximum flow of the series reaches 870 l/min.
• Spool symbol E1 across 3 switching positions with 4 ports, plus the concealed auxiliary actuation of the pilot stage.
• Internal pilot oil from P, external pilot return through the Y channel, 24 V DC supply on the 7-pole connector (6 + PE).
• NBR seals with HL fluid, mounting pattern ISO 4401-08-08-0-05, 20.64 kg.

Applications

The valve fits wherever an existing axis control with voltage command is extended, on presses, bending machines, large lifting cylinders. The separate pilot return keeps the pilot stage clear of tank pressure in the main stage. On an identical subplate this version can be swapped against the current variant F1D3M.
