The Resideo VCZAA1100 1/2 inch Sweat VC Valve Assembly is designed for hydronic applications to control the flow of hot water or chilled water glycol solution up to 60% concentration. This valve is perfect for zone control of heating and cooling systems, or in individual fan coil, baseboard radiator, or convector applications. It can be controlled by SPST or SPDT controllers, tristate, or modulating proportional controllers, depending on the model selected.
Quick open, linear, and equal percentage flow characteristics. Installation requires no tools, and actuator removal does not require draining the system. Service is done by replacing the cartridge, ensuring a factory-new condition.
