I am seeking some help and guidance to reverse engineer this video so I can build the same thing. I am building a hydroponics controller and the plumbing management is proving to be the biggest brick wall I have to get over throughout this whole project. For it to work the way I want, small AC pumps moves the water from a reservoir to a directed location, and to do this, valves are needed to plot out where the water can and cannot go. I've been through all of the Adafruit type 12vdc solenoid valves that require 3 PSI and can only permit fluid flow in a single direction. I've also given serious thought into making pinch valves from servos by using a servo with a gear or arm, and a roller on the end to swing down and pinch off the hose, but as the title suggests, I am kind of clueless about which servo will do the work I needed done. In the linked video, this is the same exact type of valve I use in my current setup which is why I'd like to pair them all with servos, but when the listed torque is expressed in OZ-IN, I am a bit lost. I fully understand torque expressed in ft/lbs, and I presume oz-in is just a scaled down representation of the same way the work is measured, but I still don't know how much twisting force is needed to twist one of those valves, but clearly the creator of that video knows.
Anyway, can someone offer some knowledge or guidance on this? The valves will be actuated prior to any water being pumped.
