Help finding book

Hi everyone, I wanted to know or where to find a book about huge hydraulic press control system (sequence, and diagram/print). I'm not new to hydraulic but new to ram, pushback admit and so one. For those who may know it better that I do. Its a system that uses water as hydraulic (98% water 2% oil) and have air hydraulic piloted valve. Anyone who can direct me where I can get the book or online documentation. Any help will be appreciated.
Respectfully yours,:)
