The Honeywell VRN2BJSA1000 is a pressure independent control valve designed for precise flow management in hydronic heating and cooling systems. This valve automatically adjusts the flow based on changing piping pressures, ensuring stable temperature control. It is suitable for systems using hot or chilled water and can handle solutions with up to fifty percent glycol.
3/4 inch NPT connection
Effective flow rates of seven gallons per minute
Operates on twenty-four volts AC
Product Highlights
The valve integrates a pressure control cartridge that balances flow and temperature throughout the system, optimizing energy use.
