Are all on-off valves solenoid valves?

It’s a relatively basic question, but I don’t know the answer, so I’m asking for help. Thank you! ! !
Definitely not; there are many types of control valves, such as gate valves, plug valves, ball valves, and so on. Valves used to open or close the flow of medium in pipelines should all be considered control valves.
Not necessarily; valves with a diameter of DN15 or larger generally come equipped with pneumatic actuators.
The control of process gas generally relies on solenoid valves, while for process control valves with larger diameters, ball valves, butterfly valves, and similar types are used
