This Resideo Motorized Zone Valve is a precision-engineered device designed for hydronic heating systems. It features a 1/2 inch sweat (SWT) connection, which is a standard size in the industry, ensuring compatibility with most systems. The valve operates on a 24-volt (24V) power supply, providing reliable and efficient performance. Its diverting (DVRT) functionality allows it to control the flow of water in two directions, enhancing the system's flexibility and adaptability. The valve has four control valves (4CV), offering precise control over the heating system's operation. Additionally, it comes equipped with an end switch (W/ESWITCH), which enables it to communicate with other devices in the system, such as thermostats or boiler controls, for seamless and coordinated operation.
