Description
The Resideo V2040DSL15 is a thermostatic radiator valve engineered to deliver precise, automatic temperature control in hydronic and one-pipe steam heating systems. Its 1/2 inch NPT straight body configuration makes it the ideal choice for inline installations such as baseboard heating and straight-run radiator connections. By continuously sensing room temperature and modulating hot water or steam flow, this valve maintains consistent comfort levels while reducing energy waste.
Constructed with a nickel-plated bronze body, the V2040DSL15 is built to withstand the demands of long-term operation in both residential and commercial environments. A replaceable internal cartridge simplifies maintenance and extends service life without requiring full valve replacement. Compatibility with T100 series thermostatic actuators ensures seamless integration into existing or new hydronic control systems.
