Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9EK31/F1M - Bosch Rexroth R900746205

In large plants thirty metres of cable between cabinet and valve are quickly reached, and a voltage signal loses accuracy over that distance. This 4WRZE25 therefore takes its command as a 4...20 mA current and sets 220 l/min nominal flow at 350 bar.

Benefits

• The 4...20 mA interface stays accurate over long cable runs and reveals a broken wire.
• 220 l/min nominal flow for medium axes, up to 870 l/min maximum.
• Internal pilot supply saves the feed line, external return relieves the pilot chamber.
• On-board electronics in the valve, 24 VDC supply through one connector.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid.

Applications

The valve is installed in widely spread plants such as sawmills, recycling presses and steel construction machinery, where the control cabinet stands far from the actuator. Size 25 with the ISO 4401-08-08-0-05 pattern is the usual interface in this power class. The weight is 20.2 kg.
