Description
The NTI Boiler 64980198 3-Way Motor & Cartridge Valve Kit is a clean essiential control assembly used in boiler systems to regulate the direction of heated water flow between heating circuits and domestic hot water production in HVAC systems. It combines a motorized actuator with a replaceable valve cartridge for switching and modulating flow paths. It is commonly installed in commercial systems to manage space heating loops and indirect water heating tanks. Within the system, it redirects hot water based on demand signals from the boiler control, supporting temperature control, efficient heat distribution, and coordinated operation between heating zones and domestic hot water supply.
