Thermostatic Valve
A Thermostatic Valve is a special type of control device used in heating and cooling systems that automatically adjusts water or steam flow based on temperature. Think of it like a smart tap that knows when to let more or less hot water through to keep rooms at just the right temperature. These valves are commonly found in radiators, shower systems, and industrial heating equipment. People working with these devices might call them "TRVs" (Thermostatic Radiator Valves) or "TMVs" (Thermostatic Mixing Valves), depending on their specific use.
