Manual valves are primarily used to stop and start the flow (block or on-off valves), although some designs can be used for basic manual throttling.
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller such as pressure, temperature, and liquid level.
