This Resideo Zone Valve is a normally open (N/O) device with a 1-inch National Pipe Thread (NPT) connection. It operates on a 24-volt power supply and has an 8 cubic feet per minute (CFM) flow coefficient (Cv). The valve is designed to control the flow of water in a heating or cooling system, and its normally open configuration means that it allows fluid to pass through when no power is applied. The NPT connection ensures compatibility with standard pipe fittings, while the 24-volt operation makes it suitable for use in low voltage systems. The 8 Cv rating indicates the valve's capacity to pass fluid, with higher numbers indicating greater flow.
