Proportional Directional Valve 4WRZE16W8-125-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901465690

A command value carried as a 4...20 mA current signal stays interference-proof even over longer cable runs from the control cabinet. The 4WRZE16W8-125-7X/6EG24N9K31/F1D3M accepts its command in that form and meters 125 l/min nominal flow at a maximum operating pressure of 350 bar.

Technical data

Applications

The pilot-operated spool valve works on axes of presses, test rigs and forming machines that call for 125 l/min. The external pilot circuit keeps pilot pressure independent of the working pressure of the axis, and the pressure reducing valve in the pilot stage limits it to the permitted level. A concealed auxiliary actuation is available for commissioning and service.
