Description
The Belimo ZONE220S-35 2-Way 3/4″ Zone Valve Sweat 3.5 Cv is an essential flow control part used to regulate water circulation in heating and cooling. It operates as a two-position or modulating valve when paired with an actuator, allowing or restricting flow through a single water path in HVAC systems. In applications, it is installed in fan coil units, radiant heating circuits, and chilled or hot water distribution systems to manage zone-specific temperature control. The sweat connection provides a direct soldered integration into piping networks, supporting consistent flow regulation and accurate system performance in clean installations.
