I am needing to adjust the Aux Pressure on a 75G for a Blue Diamond Plate Compactor. Specs are 2700psi and max 10 bar return pressure. Does it make sense that these pressures would just be adjusted at the circuit relief valves for spool 1? Or will there need to be adjustment made to the pump 1/pump 2 relief adjustment? Planning on connecting pressure guage to the pressure and return lines of the aux system to adjust these pressures at the circuit relief valves 108/109 on attached file.
Welcome to HEF Gator . You will be able to adjust the spool 1 circuit relief for 27OO psi on the pressure side. If you put the selection valve to one way flow (which sends the return oil back to tank) you should be able to get the return pressure lower than the maximum 10 bar (145 psi).
Thank you for the quick response Diesel Dave! I appreciate it! Look forward to contributing and learning from this group.
