Description
The Belimo ZONE315N-35+Z24NC Zone Valve controls fluid direction by switching flow paths within hydronic systems to regulate heating or cooling distribution. With a 3-way normally closed configuration, 1/2 inch NPT connection, 3.5Cv flow rating, and 24V operation in HVAC systems, it manages fluid routing based on control signals. It works through an actuator that shifts valve position to open or close ports, directing flow as required. Mounted within piping assemblies, it interfaces with system lines to maintain controlled circulation. Its balance flow distribution, supports system zoning, and maintains stable operation.
