The Caleffi Danfoss Straight TRV Body (105-1502) is a professional-grade thermostatic radiator valve designed for commercial and residential central heating systems, ideal for building managers and heating technicians looking for precise flow control. It provides the essential benefit of granular temperature regulation for radiators, heated ceilings, and fancoils; however, users should note that the thermostatic or manual controller head is typically sold separately and must be compatible with the Danfoss connection interface.
