Schneider VT2323G23A020 NPT Normally Open Zone Valve 24V 3/4 Inch 2W

"The Schneider Electric (Erie) VT2323G23A020 is a 24V usually open zone valve used to control fluid flow in HVAC systems. This 3/4-inch valve has a two-position spring-return mechanism. In its usual state, the valve is open, enabling fluid to flow. When activated with a 24V AC signal, the valve closes, halting the flow. This electrical functioning allows for easy integration with thermostats and control systems. Zone valves are widely utilized in hydronic heating and cooling systems. They are installed in zones, which are discrete portions of a building that require individual temperature management. By adjusting the flow of hot or cold water to each zone, the system can provide tailored comfort while also improving efficiency. For instance, a zone valve can turn off the flow of hot water to a room that has reached the desired temperature, preventing unnecessary heating.
