Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900748463

A long signal line across a plant cannot carry a voltage command without losses. The 4WRZE25E1-325-7X/6EG24N9EK31/F1D3M therefore accepts 4 to 20 mA as its command value, which the on-board electronics turn into up to 325 l/min rated flow at 350 bar.

Benefits

• Command value 4 to 20 mA instead of voltage, the current signal stays stable over long runs between cabinet and valve block.
• 325 l/min rated flow, 870 l/min maximum, operating pressure up to 350 bar in size 25.
• Spool symbol E1 with 3 switching positions across 4 ports, pilot stage with pressure reducing valve, concealed auxiliary actuation.
• Internal pilot oil supply with external pilot return, 24 V DC on the 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-08-08-0-05, NBR seals, HL fluid, 20.64 kg.

Applications

The valve suits rolling mills, injection moulding machines, power units whose controller sits several metres away. A current interface also reveals a broken wire, because the command value starts at 4 mA rather than at zero. On the oil side the same subplate applies as with the voltage versions of the series.
