Caleffi now provides an industry-exclusive five-year warranty for installing a Z-one Zone Valve with a ZVR Z-one Relay. The Z-one Series valves are used to automatically shut off the flow or redirect hot and chilled water in hydronic heat and cooling systems.
The ZVR series of controls is used for zoning up to six zone valves (model-dependent) along with a system pump, secondary pumps and primary pump.
