Description
The Resideo V2040ESL15 is a precision-engineered thermostatic radiator valve built for reliable, automatic zone temperature control in hydronic and one-pipe steam heating systems. Its vertical angle body design accommodates installations where piping changes direction, making it an ideal solution for tight or complex plumbing layouts. The valve continuously senses ambient room temperature and modulates hot water or steam flow to the radiator — delivering consistent comfort while reducing energy waste. Constructed from durable brass with a field-replaceable internal cartridge, the V2040ESL15 is built for long service life and straightforward maintenance. Compatible with T100 series thermostatic control heads, it requires no electrical wiring, simplifying installation in both residential and light commercial applications.
