Can the valve be controlled directly by a level gauge without using a PID controller?

As long as it is necessary to prevent water from overflowing in one tank, can the output signal from a level gauge be used directly to control the operation of the valve?
It’s completely possible, as long as the valve can receive signals from the level gauge and be able to perform control functions.
It can actually be made to use a floating ball for control, which is simple and practical.
Level feedback, after being processed by the DCS, can be used to directly control valves equipped with positioners.
Just a \"stainless steel float valve\" is needed; you can search for it on Taobao.
