What is the purpose of installing this valve on the common pipeline?

As shown in the figure, these are the pipes of the shared system. Why is a self-controlled valve installed between the supply and return main pipes for the ethylene glycol refrigerant? Is there also a wire connected to the temperature measuring instrument on the compressed air pipeline? I hope everyone can give me some guidance; thank you.
