How does one know about hyd, you say, manuals, books, DVD's, hyd courses, YouTube videos and you can learn a lot on forums like TBN.
Also, just your questions here and someone should be able to answer.
Your manual should tell you about your hyd system.
But anyway, you and your dad's tractors are open center hyd systems, where the pump is pumping all the time the engine is running.
All valves are in series.
The pumped fluid passes through all valves to tank when the levers are in neutral.
When you move the levers, you re-route the fluid to the hyd component be it a cyl or hyd motor.
Some of the hyd valves are for convenience. You select the type valve/spool to accomplish the task.
If you want float, select a spool that has float.
If you want to control a hyd motor, you select a motor spool.
If you want regen, you select a valve with a regen spool.
A lever type valve will let you feather the valve for slow and precise work.
A solenoid valve works fine in some situations, and is usually full flow.
The GPM's pumped is dictated by the engine rpm.
You can probably get everything from here.
