Hydraulic valves are necessary for many different hydraulic mechanisms. There are many different uses for hydraulic mechanisms. The biggest use for hydraulics allows the lifting of heavy objects with little effort. Without the hydraulic valves, this concept would not be possible.
I believe all were hydraulic.....
Hydraulic pressure is the force exerted by a hydraulic fluid within a hydraulic system. It is created when a pump pushes the fluid through valves, hoses, and actuators, resulting in a mechanical force that can be used to perform work. Hydraulic systems are commonly used in machinery and equipment that require precise control and high power output.

No they are hydraulic valves and are self adjusting.
If it has hydraulic lifters, you do not adjust the valves.

The basic and most common functions of valves in a hydraulic system are to regulate the flow and pressure of liquids. There are varieties of valves as per their functions such as: Isolation valves, to open and close the system, Flow control valves/Balancing valves, to co control the quantity of flowing liquid, Pressure relief valve, to release the excess pressure from the system, etc.
Assuming you're talking about hydraulic valves for cars, the replacement part prices seem to fall in the $150-$250 range.
no, the valves are self adjusting using hydraulic lash adjusters.
replace the hydraulic tappets in the rocker arms, valves are non adjustable.
No it isn't possible since they are hydraulic valves and are self adjusting.
