Description
The Johnson Controls VG1245AD+9A4GGA 1/2″ 2-Way NSR Proportional Valve is a control that varies the fluid flow in accordance with a 24V signal with proportional positioning in HVAC systems. It has a 1.2Cv flow coefficient that gives accurate results in chilled or hot water in hydronic heating and cooling loops. It is installed in piping, either in air handlers, boilers, or fan coil units, to be used in building automation and control systems to regulate flow based on temperature requirements. This valve is an essential flow component that maintains constant temperature and efficiency.
