Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900703327

On axes that move little oil, the resolution of the command input matters more than raw flow capacity. The 4WRZE10W8-25-7X handles a 25 l/min nominal flow in size 10 and accepts its command as a 4...20 mA current signal, which stays immune to pickup over long cable runs.

Benefits

• Nominal flow of 25 l/min in size 10, connection diagram ISO 4401-05-05-0-05.
• Current command 4...20 mA on on-board electronics, a broken wire stays detectable.
• Internal pilot oil supply and internal return keep the piping to the four main ports.
• A pressure reducing valve in the pilot stage holds pilot pressure independent of system pressure.
• Maximum operating pressure 315 bar, maximum flow 170 l/min.
• FKM seals, concealed manual override, UKCA declaration for electromagnetic compatibility.

Application

Typical places are feed axes on machine tools, clamping and positioning cylinders and test rigs with slow ramps. The valve sits on a subplate to ISO 4401-05-05-0-05 and needs no external pilot lines. At 8.37 kg it can also be used on moving manifolds.
