Description
The Resideo V2040ESL20 is a thermostatic radiator valve engineered for automatic, precise temperature control in hydronic and one-pipe steam heating systems. Its 3/4 inch NPT vertical angle body configuration makes it the ideal choice for installations where piping must change direction upward or downward at the radiator. By continuously sensing room temperature and modulating hot water or steam flow accordingly, this valve delivers consistent comfort while maximizing energy efficiency — no electrical wiring required.
Constructed with a durable nickel-plated bronze body and an adjustable, replaceable internal cartridge, the V2040ESL20 is built for long service life and straightforward maintenance. Compatibility with T100 series thermostatic actuators provides a complete, self-contained control solution for residential and commercial heating applications.
