Description
The Belimo ZONE220S-50 is a factory-matched, 2-way sweat zone valve and actuator assembly engineered for reliable hydronic zone control in residential and light commercial heating and cooling systems. The integrated design pairs a 3/4-inch sweat-end valve body with a Cv flow coefficient of 5.0 and a dedicated electric actuator, eliminating the need for separate valve and actuator selection and simplifying installation.
Belimo’s ZONE series is widely trusted by HVAC professionals for its robust construction, consistent performance, and ease of field installation. The sweat (solder) end connections allow for clean, leak-free integration into copper piping systems, making this valve ideal for fan coil units, air handlers, and hydronic zone distribution applications.
