My hydraulics is basic at best and have been asked how we can control a 0-80 lpm pump when we only have the output of a NG6 proportional valve (0-40 lpm) valve to do it
We have access to system pressure (200 Bar/150 Lpm max) so what i really want is to use variable / proportional pressure to give proportional access to the system pressure/flow
Is this feasible? Is there a valve out there just waiting for me to purchase it? In my mind i see the proportional pressure driving like a spring return piston which is in turn giving access to "full fat" flow
Much thanks in advance
PS If there is a go to resource for all things hydraulic i'd very much like to hear about it !
