Dear all,
I am developing a manual punching machine to be automatic. It has two directional valves , one for punching up and down , the other is remote valve right and left , so there are 4 relays. I want to understand the hydraulic circuit , how it works , why the two valves must be on together to move the head and what is the difference between right and left ?
Thanks a lot
Fareez
