Most thermostatic valves are only needed in a domestic water system that has a device to heat water (such as waterheater). These valves will control the set temperature of the valve and only allow the degrees of set temperature and colder. Example lets say you have a thermostatic shower valve with the cold side being 52 degrees F and the hot side 140 degrees F and the valve set at 120 F , this valve will only allow the max temp of 120 F out of the shower head but does not control any cooler temp only the max temp in which it is set. They also have thermostatic valves that control any temp but mostly for controlling hot water to prevent scalding. Pressure balanced valves will not control temperature only pressure and equals the same pressure from hot and cold sides.

That is a fill valve and is part of the ballcock system. When someone pulls the lever, that pulls the chain and lifts the flush valve flapper and empties the tank into the bowl. That causes the float to drop, opening the fill valve and allowing water from the supply to enter and refill the tank.
How does the anti syphon valve work?
The anti syphon valve works by only allowing water to flow in one direction. For irrigation purposes, it prevents water from the system from being siphoned back into the water supply line.
Where is the prv valve?
The main Pressure Reducing Valve (PRV) can typically be anywhere between the City Water shutoff valve by your water meter (if external) and the first "tee" in the water supply system. Though quite often it is near the main building shutoff valve inside the home.Some fixtures or appliances have their own PRV, like a hydronic heating system.
