In the attached picture, you can see a hydraulic schematic of our installation with a proportional valve (Atos) with integrated force control (pressure transmitters from up- and downside of the cilinders are connected to the valve electronics.
My question is, will the proportional valve be able to fully control force on the cilinder, considering the check valve (nr12 ont the drawing)in the hydraulic line to the cilinder.
Someone told me the valve will never be able to reduce the pressure on the bottomside of the cilinder.
But won't there be pressure on the other side of the cilinder at that moment to open the check valve?
Please share me your hydraulic experience?
