Excellent. Thanks

Oh ok thanks! Seems like you are illustrating a Rexroth pump in the a10v series. Imo a shuttle valve on the A and B port on the float dcv could add more flavor and you can just connect the downstream port of the flow control valve to the P port of the dcv. Only thing that I can comment a bit is that when the pump runs it destroke but the flow is always present and at maximum designed/allowed destroke the pump is still pumping fluid out and can’t be zero which can be observed from the case drain line. Anyhow it’s always good to have more hydraulics video.

I kept load sense 200 and maximum 3000.but when running the machine I am getting maximum pressure 1500psi only.if I increase load sense up to 750psi the maximum pressure increasing near 3000 psi.why maximum pressure increasing when load sense pressure increases

in your machine, if you only need 1500PSI to move the load that is all the pump will generate. That is what a LS pump does, only generate the amount of flow and pressure called for by the control valve (flow) and load (pressure). If you increase the margin pressure in the flow compensator to 750PSI and run the application that requires 1500PSI, the pump has to generate outlet pressure of 2250PSI to provide enough pressure to operate the flow compensator spool. Increasing the LS spring setting to 750PSI has nothing to do with the setting of the Maximum system pressure dictated by the pressure compensator spool/spring. If it does, you need to change the whole control module out because there is a stray load sense pressure entering the spring chamber of the pressure comp spool and that's not a desirable situation at all.
