Sharing my knowledge on selector valves

[mrDumplingslov3r]

typical case/ingersoll tractors does use a 2 spool tcv, one high pressured valve for driving another is low pressured for lifting attachments. if you want to run a 2nd cylinder say for a 3point hitch off the existing midlift valve you can just connect the new cylinder's lines to the current circuit and they will both move together. though its best to be able to control each one independently, but know that there are 2 types of selector valve a 6port and a 3port. A 6port selector valve lets you swtich the flow of the hydraulics between 2 different cylinders. It seizes the lines from the TCV and routes them to either one. so with a 6port valve you can completely isolate and swap between 2 circuits like a 3pt hitch and mid lift. This will lock the unused cylinder in place. 6port is more ideal but a 3port is simpler and ofc cheaper. A 3port selector valve can simplify hydraulic manipulation by diverting only a single line from the tcv despite only changing half the flow it effectively switches between hydraulic circuits just like a more complex valve. okay so heres how a 3port selector valve works on hydraulic cylinders, when i choose a circuit say for example the 3pt hitch the other cylinder like the deck lift, effectively locks. evevn if its 'drop' chamber can release oil, the lift chamber is sealed to prevent movement coz oil resists expansion. so the deck cylinder stays in place. then if i use the TCV to lower the 3pt hitch, pressure goes to the drop chamber of both cylinders. Though due to the selector valve, only the 3pt cynlider's up chamber can release the oil back to the tank. this will make the 3pt cylinder retract while the deck cylinder remains locked. so basically the 3port valve lets you choose which cylinder moves by controlling the oil flow to one side. so spare you a mean amount of time a 3port selector valve is inferior compared to the 6port, but ofc good enough to most considering the price and other factors. And to add a 3rd cylinder and let it have full control on its own, you have to add a 2nd selector valve. so first we split into front and rear then the front again (deck/accessory) circuit into 2 though all we have to do to make this happen is standard 6port selector valve and a standard 3port.
Therefore, multiple manual hydraulic valves are really confusing especially it has tons of technicalities and details, i could suggest to use an electric, momentary 3port valve for a not so frequent functions like blade angling. A push button should activate it, temporarily changing the lift lever's purpose. A bit costly but easier and more convenient to use.
