Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R901055701

In extrusion the evenness of the ram feed decides the surface of the profile. The 4WRZE25E1-325-7X/6EG24N9TK31/F1D3M meters 325 l/min nominal flow for that, takes pilot oil from outside and returns it internally.

Benefits

• Nominal flow of 325 l/min supports slow, even ram feed.
• External pilot oil supply keeps control independent of extrusion pressure.
• A 4 to 20 mA current command stays stable in the electrically noisy press area.
• Spool symbol E1, 3 switching positions, 350 bar operating pressure, plant maximum 870 l/min.
• Connection diagram ISO 4401-08-08-0-05, NBR seals, weight 20.76 kg.
• UKCA conformity to SI2016/1091 for electromagnetic compatibility.

Applications

The valve drives rams, containers and shear drives on extrusion presses. It equally suits draw benches and stretching lines with a high volume demand. The internal pilot return keeps the number of oil lines at the valve small.
