Control the temperature of the reaction vessel; for steam, control is generally applied to the steam inlet. As for circulating water, should control be applied to the water inlet or the outlet?

When reviewing a design diagram, the temperature rise of the reactor is linked to the steam inlet control valve; when temperature control is achieved using circulating water, the inlet water of the circulating water system is utilized. When the heat exchanger is cooled, it is the outlet valve of the circulating water in the condenser that is controlled. Is there a difference between the inlet valve and the outlet valve?
Steam is controlled by the inlet valve; the manual valve for circulating water is usually located at the outlet, while control valves are more commonly used in situations involving water supply.
For circulating water temperature control, the outlet valve is usually used for setting limits, while for steam, the inlet valve is generally used for that purpose. Using the outlet valve to set limits can easily lead to water hammer
When cooling down, if the outlet valve is not controlled, vaporization of the circulating water may occur at low flow rates, resulting in vapor resistance.
I found the comments from netizens below to make sense. By control valve when talking about water supply, do you mean an automatic valve that regulates the inflow of circulating water?
Those downstairs say that controlling the outlet of the circulating water is usually done to prevent air blockages; isn’t there any difference between automatic and manual control?
Steam controls the inlet, while circulating water controls the outlet. Conversely, there will be disadvantages
Circulating water is generally controlled by an outlet valve to ensure the pipelines are filled with water. The steam is controlled by an intake valve
