Hydronic valves

Caleffi’s Z-one Series valves are used to automatically shutoff the flow or to redirect hot and chilled water in geothermal, hydronic heating and cooling systems. They are UL listed for plenum installations. Plus, when a Z-one Zone Valve is installed together with a ZVR Z-one Relay, both qualify for Caleffi’s industry exclusive five-year warranty. The ZVR Series of controls are used for zoning up to six zone valves (model dependent), along with a system pump, secondary pump(s), and primary pump
