Seeking automatic control solutions
Thread Content
As shown in the figure, it is necessary to flexibly choose heat exchange and cooling; it is also necessary to determine which control valves should be used to achieve automatic control
Self-control valves should be installed on each of the supply and return water branches, along with a interlock mechanism connected to the temperature control valve. I’m not from a self-control-related field; it’s just my own speculation
If it is for regulation, a three-way control valve should be used; for direction switching, a three-way ball valve can be chosen. If interlocking is required, then it is necessary to consider how such interlocking will be implemented
