The purpose of both the valves is same - that to maintain a certain level(in a vessel or tank...) Simple Level valve could be referred to an ON - OFF valve where as control valve could be referred to an analog type of valve. On - OFF valve is for a crude control of level, while control valve is used where a fine level control is needed.
As far as i know;
Regulating Valve: How much you want to pump.
Control Valve: How fast you want to pump.

pressure relief opens in an emergency to prevent damage, pressure regulator control the pressure to a predetermined value, both work on the same principal but with different usage
I believe that servo is motorized and solenoid is magnetically activated.
XV is shutoff valve UV is under control valve
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
There is no difference between check valve and NRV, both are same
They are just about the same

actuator is a mechanism that will responds to hydraulic,pneumatic and electrical signal ,it is used to control the valve that to be in open or close condition.
no you cant
They are just about the same
The term cock and valve are used interchangeably in the English language. The term cock has in large been replaced with valve with no functional difference between the two.
Control valve: Used to modify flow rate in a process control system.It has characterization: linear,equal percentage and quick opening Pressure inlet must be higher than the output pressure Regulator:Diapghram operating valve which controls outlet pressure (reducing application),control inlet pressure (back pressure) or either (differential reducing and differential relief applications
In short, More Power.
The intake valve is bigger.
three element means 1) drum level transmitter. 2) main steam flow transmitter. 3) feed water flow transmitter . in squared root. we are controlling drum level by these 3 elements. output feed to 30% control valve. or control valve.
