Proportional Directional Valve 4WRZE25W8-220-7X/6EG24EK31/F1D3M - Bosch Rexroth R901004132

When the shared return line of a plant carries pressure, the switching time of pilot-operated valves grows noticeably. The 4WRZE25W8-220-7X/6EG24EK31/F1D3M avoids this through external pilot oil return while metering 220 l/min nominal flow.

Benefits

• External pilot oil return keeps shifting time independent of pressure in the working return.
• Internal pilot oil supply is enough while system pressure is present and saves one line.
• A 4 ... 20 mA command for long signal runs in large installations.
• 220 l/min nominal flow, 870 l/min maximum flow, spool symbol W8.
• Integrated pressure reducing valve, on-board electronics, mass 20.8 kg.

Applications

Suited to paper machines, roll lines and presses with a long collecting return. Three switching positions across four ports cover both travel directions and standstill. Mounting pattern ISO 4401-08-08-0-05, UKCA conformity.
